I this is the
eight grades star reference material hack
we want our students to do this before every test once they get the star test
we want them to pull out the periodic table
in the formula chart and to start writing all
the on information that we provide in this video
this is a brain dump will allow you to you happy the star test let’s keep going
on the first thing we’re going to talk about is we want to make sure that
eat is represented on the periodic table in eat just means that
the atomic number equals the number of protons
equals the number electrons
you put that right up there by be given boxing pitu
number two were gonna point in a row right at the atomic mass
and we’re going to denote that means on
protons plus neutrons stand next to you right
on your interview number three we’re going to talk about mass now our scheme
and now
so me n is an acronym that means atomic mass
minus the atomic number equals
the neutrons so you’ll see the
im in mass in the a an atomic number
in the in in neutron or are an acronym for
this little many formula and you can even certain let me in
you’re ever given a problem we need to find neutrons
begins plug in your information given in government fourth
real time I were the valence electrons are on the PRT went hiking determine how
many be words like Jones Beach particular element hands
someone right valence electrons up at the top here
demanded ransom a rhodes to
each of the groups and families just a couple the group Mac and Roger each one
of them
and our circle the group number or the park a big group number that represents
valence electrons notice that group 1&2
are also one mailings like John into man’s like Charles
then we start working online group 13
through a team and Rockaway rose over maybe 1318
and we have to drop to one of to make sure that
we have the correct number valence electrons sovereign example on this one
is group 13 but only three
valence electrons and in the next will be grouped
14 but only for Palin’s like chance
so everything in that group were in that family
you are the same number valence electrons in the same reactivity
II now we’re gonna move up to talking about groups or families a little bit
more some
above about 16 group 16
we’re gonna write
on these are called groups or families in the Thomas Circle
this particular grouper family what this means is that
everything in this group or family has similar
properties and similar reactivity
so I’m gonna also put a
box around 16 to show that that’s the
group number know when she confused the group number with the
mainland’s lecture on them this is actually the phone number there
so in this particular case oxygen sulfur
on in so for selenium to learn they’re all
going to be I’m so have similar reactivity
are up moving on we’re going in now
go over to you the roads which are called
periods on the periodic table
make sure we have reactivity on here because that’s what that
group number tells us meals electrons
and so now we’re gonna move over to the periods and
these are the rosies with the horizontal rose going across the beer cocktail or
and they tell us on couple with everything details number
energy levels and then tell us the number
energy shells in actual more
model so I was gonna label periods cross the
side here output in parentheses energy levels
he and energy shells you be real surprised how many questions will pop up
on the star test that will be answered by just having this room bring dumping
now we’re gonna move down to the bottom of the periodic table
we’re going to talk about reactivity real quick
I’m gonna draw big long aerogel right
to left and I’m going to label it
increasing reactivities has the Aero
moves toward the lapd rise the group moved toward the lapd
they get more reactive so is gone awry increasing activity down towards the
bottom
the most reactive group for family
on the periodic table is group one so many despite a littles
I most reactive down there so I know that those are highly reactive
they have one valence electron and they want to give nothing away as fast as
possible
may react
very violently with a lot of different other elements
now going back to the other side group in
team these are the most stable someone right most stable down here
and this group has a special name its call
the nowww gases so shriner need
the the on element raid on a mission right noble gases just in case that
happens that pop up on a test but these guys are real stay with me
they’re not giving any electrons away their electron shells are totally fall
II so the black table strongly marked up
now we want to go to back to the top the periodic table
you wouldn’t start talking about different other chemistry principles
summer focus in on this top left corner and
on room first talk about compound
known as glucose which is c6 each 12
06 gonna make some comments about it real quick seen this before shop on
previous start ass
so three elements it has three elements and you do that by counting the capital
letters
carmine hydrogen and oxygen so
three elements out to the side there and it has a total
up 24 harlem’s we do that by counting the subscripts that’s the little number
behind each other the particular elements
if they’re is not a number there then it’s implied that is one
I’m you cannot how the latter and not have
happens so it has to be a one this case
is 24 happens I the next thing you know
you know that chemistry is the rap
acronym that we gave you in this is talking about balance
on balance equations on each side
the Aero there are reactance on the left
and products on the right in order to be balanced
they have to have the same number on each side
same number Adams we call this route because
there’s an are reactant the he stands for the
a row in the P stands for the product right
Stoli balance than those numbers would only matchup
okay now asking the subatomic particles
we’ll be talking up protons neutrons electrons first we’re going to talk
about protons
protons am realistic
charge which is positive near found
inside the nucleus zooms in a little bit more so you can see it
right and then next we have a neutron
which is
a negative charger no excuse me and no no charge
are neutral charge and near found inside the Adams well
and then the electron
which is negative and brown
outside the nucleus also wanna make no
top two the protons and neutrons
make up the most mass up the Adam
this is where all the masses found in the AM electrons
have tiny tiny little be a math mass
but not that much muscle mass comes from the protons and neutrons
in and she moved to the top right corner of the sheet
renowned talk about metals middleweights
and nonmetals some metals recalling those
on the left side appear table so basically anything to the lapd beam
the staircase on the periodic table were saying
is him at all an answer my own properties air she never shiny luster
a I means they’re shiny when you look at omnis the way the light
reflex of them and then they are valuable which means they can be pounded
into sheets
they are also good conductors
in their poor insulators could also mention that there
ductile as well means they can be
polled into a wire you’ll see in copper wire
in all your electricity run your house your school
right next to talk about the middleweights in metal lloyd’s
are found on usually
touching this staircase on the pier on tables and touching that black line
looks like a staircase
on the periodic table in all those are metal woods except for one which is
aluminum in ashes when you have to remember is
a metal you think aluminum it does look like it has lots of properties in metals
make sure that you know that that is actually in metal justice that pops up
alright so metal what’s up their properties both
marking a list all the problems you just you just you know their properties both
they could be
shiny in a QB brittle cell
alright and then lastly we have non metals nonmetals
are on the right side iraq table general region not generally the
are too right the staircase and they are
mostly gas there are some exceptions that just like everything in science
and they are dole meaning they have no shine to them
something chalk when you think a bill you cannot talk is not an element has a
don’t actually near good insulators in the
are poor conductors
writes that this is the periodic table you can see it didn’t really take that
long to
to fill this out I don’t all my knowledge
I don’t appear on table in this is going to help me answer
many many many chemistry questions that can be thrown at you on star test
I’ve got thirteen different concepts on you
I would guess that if you knew all of this
that you have would have him very very good shot
passing stars knowing this part of the chemistry we’re going now
flip it over to the back and work on the formula chart
in a couple of other models that we like you did wrong
