when an Adams electrons are in an unstable arrangement they will bond with
0:06
other unstable atoms in order to rearrange their electrons
0:11
and become more stable they do this in order to get
0:14
octet all they let Shaw of electrons
0:18
since medals have fewer bailouts electrons to begin wit
0:24
they always prefer to give away a pair electrons
0:28
when they lose electrons they become more stable
0:31
and they become positively charged this means that they have now
0:37
or a positive IOC we call that katayan
0:44
since nonmetals had more valence electrons to start of
0:48
they are already closer to having an octet and they're already closer to
0:53
being stable
0:54
so they want to hold on to their electrons
0:57
the hairy tightly they're not going to like anyone comment steal away on
1:02
electro rock
1:06
aspect of nonmetals holding those electrons so tightly
1:10
this is called electronegativity nonmetals have a high electronegativity
1:15
value because they hold their electrons very tightly they don't want to give
1:19
them up
1:20
but metals have a very low electronegativity
1:23
values they don't need the electrons they'd rather give them away
1:26
anyway nonmetals have high electronegativity values
1:30
metals have low electronegativity back use
1:34
instead of giving away electrons
1:38
nonmetals go hunting for more electrons
1:41
they want to gain enough electrons to get said there are
1:45
Ted when an anime gains electrons
1:49
it becomes negatively charged this means it is formed and negative I L and that's
1:54
called and
1:55
and I down
2:00
with them at all and now I'm at all
2:02
interact with one another they form iconic Barnes
2:06
its the metal atom is positive and that not meant a lot on his negative
2:11
their charges attract one another so they stick together
2:15
forming a new chemical compact
2:24
went to non metal atoms in Iraq date for
2:27
Kobe let bonds since both atoms are greedy for the electrons
2:33
but both Adam still need to gain more electrons in order to be stable
2:38
the two nonmetals why actual each share their electrons with one another
2:43
this sharing forms bonds that hold the atoms together
2:47
forming another kind of chemical compound
2:54
but what happens when to
2:57
metal atoms need to become more stable they both want to get rid of their
3:01
valence electrons but
3:03
there's no not medals to come around and pick up the bass n
3:06
take those extra electrons so
3:10
they just lose them anyway metal atoms give of their electrons no matter what
3:16
because they are so desperate to become more stable
3:19
by if they are only other metals around
3:23
they need to help each other out so the metal atoms play a kind of ping-pong
3:28
game
3:28
with the electrons when one battle spirits of its electrons
3:32
the other catches them but instead of holding on to them but not medals to you
3:37
it spits it right back so the two metal atoms are
3:41
passing the electrons back and forth back and forth constantly
3:44
this is happening so fast and it happened so much that the Adams end up
3:50
feeling like
3:51
they don't have any electrons at all so all of the metal atoms end up more
3:56
stable
3:57
and in the process the form another type of bond
4:00
these are called metallic bonds since no one wants the electrons they just
4:08
in-depth
4:08
loading back in force very rapidly in this space
4:11
in between all of the metal adults this floating mess up electrons
4:17
is called the sea up mobile electrons
4:20
meaning that there is a constant flow of electrons moving all around the metal
4:25
atoms
4:26
but never really staying attached to any of them
4:30
this flow is what gives metals
4:33
all up there are important property in metals
4:36
the electrons are free to move about the metal atoms
4:40
virtually become positive I'll squad
4:43
attracted to the electrons between the electrons
4:48
alike aghast it fills the spaces between
4:51
the atomic ions Holden together
4:56
rule metals a shiny show
4:59
most looks Silva because they reflect all wavelengths
5:03
the photons
5:06
lump-sum light the free-floating electrons
5:10
which by great producing a matching photo on
5:13
we see as a reflection
5:17
of electrons move fast
5:20
and carry large amounts of kinetic energy this is how heat is conducted
5:25
from a hot spot
5:26
too cool regions
5:29
it would be more random group
5:33
the free electrons metals good conductors of heat
5:37
and electricity
5:41
the only exception is gone good conduct repeat
5:45
not electricity
5:50
the electron blanket
5:51
allows the metal to be worked into different shapes
5:56
if the electrons were fixed in position the missile would not yield as
6:01
visa truth
6:07
you
6:07
under load the ocean electrons can move
6:11
easily allowing the atoms to rearrange themselves
6:18
to prevent the atoms moving is easily different sized atoms can be added
6:22
to hold them there as in place be this way
6:29
on could be strengthened by adding carbon
6:33
to produce steals
6:36
missiles can be made more rigid by I'm going with elements from the Middle
