the purpose of this scandal is for u for us to take a look at
what adams are
and it's distinguish between adams
and
or holler adams and elements related
another very important part of understanding the makeup of matters
understand what it
so what is a molecule and hollow ism adam
anemometer hill
related
a fourth term or concept is com park
so another purpose to this news
freed understand
between a molecule compound
and poverty
the relationship between an element
but the center of focus really of our study for the next couple of months
is going to be
that right there
so let's take the adam first
here is a
picture of a and
and diamond is a type of substance that's a pure substance
meaning it's only made up of one
of adam
or one
of thing
or particle
and there it is
home obviously has to be a large for you see that let's say that that little
quite circle
the smallest particle of that diamond
which we would call an adam so let me in large it therefore easily concealed
better
so one of the ways in which we can
to finance adam is that it's the smallest particle
of any type of matt so small sparkle of all matter
should be simple enough to understand
so how is it related to
elements
well
is for you to see again that that white circle there is represents an atom
that's an atom
is an element
so one way in which we can define an element is that it's the simplest type
all pure substance once again
appears substance is something
but only contains one type of particle
and you can see from that picture there of an element
wiley adams
or the same
another way in which you can define it element
is any substance that cannot be broken down into a different
or into another substance
so as you see i have just
broken off a piece of that element
it's still that same element is meant
and you can tell that because it's made up of the same types of asp als light
balance
i can even break it down
even further
that's still an element is an
because the only thing that makes it up is that
same pierce upset same adult
so another way in which you can
define adam is that
it isn't marched particle
of an element
that has all the properties
of adult all the physical and chemical properties
of that one small shit
adam on the right
has all the same properties
is the rest of the element over on the left side of the screen
so an adam is the smallest particle
of our matter
you can also be defined as a small sparkle of an element that has all the
properties
of that element that phrase
that has all the profits of an element
aki fridge there
so here are a few questions that will help
clarified your mind hopefully
and similarities and differences between out of developments
the first question is are elements made up of outs will here are the elements
that we just saw the last
slide
so yes
elements were made up about
how many different types of elements exist
the weight of discover this is to look at a particularly elements
for every
block that you see there
for every
the productivity elements
represents a different element
this is not quite the most current productivity elements
we have somewhere in the neighborhood of a hundred and sixteen or a hundred and
seventeen
different types of balance that exists
in our world
how many different types of adams
exists
you look at the same chart because not only beseech tyler each box on this
chart represent elements they are to represent
different types of adults
so for example you have the element
hydrogen and helium
first-world
there are also different types of adducts
so
that the question are the terms
adams and elements
interchangeable
the answer to that used yes
you have to remember
that adams are actually the smallest component
of that element
epic system molecules
here is a
picture of a people vice
obviously melting
now ice is as you probably know
is each to all
we can say that it's a molecule or combo
so damaged emis let me show you
one of those markets and so let's say that that represents
in molecule
of advice or water
let me in large that for you so you can see that that's actually not really the
molecule of water but it is a molecule
so molecule can be defined as two or more adams
that have chemically
combined not just combined but
chemically combined
and at this point i don't expect you to know what
chemically combined actually means
but hopefully from that picture you can kind of see that the adams have joined
the each of it
so there is a molecule
let's relationship between a molecule in the compound
well the best way to do that
is to
direct your attention to that ma kildare
if that's a molecule
and the compound distance
so the relationship that we saw between adams and elements is the same exact
relationship
that we see between molecules and compounds
one of the definitions of a compound can be
a substance
made up of two or more elements chemically combined
boy that sure sounds like
the same definition or almost the same definition as a definition for a
molecule
to a more adams chemically combined is a molecule
to a more elements chemically combined
is a compound
so i could break this compound down
into something smaller like idea just there
is that still that same compound
well of course it is because it's made up of the same
kind markets and i can even break it down into its individual molecule
so likely get with adams we can also say that molecules
by the smallest component
of a compound
and here's a key phrase again
that has the same properties
of acecomm pop
that molecule that you see there on the right
has the same properties such as density
boiling point
freezing point
or want to insert there
cab molecule has this very same
cannot go and physical properties of the compound
that you see left over on the left hand side of the screen
so here's a link clarifying questions
to help you understand even further
similar recent differences between molecules and cumple
are compounds made up of molecules
well there's that
knows that compound that we saw the previous page
and if we remove one of those the smallest component of it bs that some
molecule so compounds
definitely made up of molecules
by the terms molecules in compounds interchangeable
yes they are
just like adamson elements are
molecules in compounds can be used in your change of me but remember
molecules business models component
of a compound
that's still has the same properties
of that compound
are compounds made up of adults
it's take a look at that there's a
