Ionic compound formation - Metal & Non Metals, Chemistry CBSE Class 10 Video Lecture

hello friends this video on metal and
nonmetal part 12 is brought you by exam
fear calm no more fear from exam before
watching this video please make sure
that you have watched part 1 to part 11
so with this let us understand the
formation of any see so as I have told
sodium has one extra electron in this
shell and chlorine has 6 1 2 3 4 5 6 5 7
it needs one it needs one and sodium
want to lose this so what will happen is
sodium will immediately lose its
electron this electron will go to
chlorine and chlorine will become CLS
same electron will go to chlorine well
and that is nothing but this electron
will get transferred here so with this
our happens is this becomes n a class
with no outer electron here and this
becomes CL minus with 1 2 3 4 5 6 7 & 1
we got from chlorine so I made in the
dot and the one which which chlorine has
its own I made in the cross just for you
to understand but there is no difference
actually
alright lectrons so there are 8
electrons now here 7 which chlorine hand
and 1 extra from Sonia and thus if you
see that both are stable but now if you
see that this guy got a positive charge
this guy got a negative charge and both
attracts positive attracts negative and
thus there is a bond form right and this
type of bond is called ionic bond
because they are all ions and if you
that's why if you if you have this NaCl
and you put in the water
this becomes na plus ions CL minus ion
it breaks it breaks into ions and that's
why the normal the the water right the
pure water won't connect it electricity
but if you put sodium chloride or salt
in that it will correctly
you get the free ions to kinetically T
that's what happens when you put in this
it becomes iron and why it becomes iron
is maybe Alex clean this h2o is like
this right and in this case there is a
sharing done the electrons are not is
this example of a covalent bond actually
right so this guy is slightly positive
charlie is slightly negative charge
right so this guy attracts the chlorine
and this guy attracts O'Neal and that's
why that the reason why the ions bring
and we'll explain more this when we
learn the covalent bond and the
structure of water that is specifically
but just for knowledge because I told
you that why this ionic bonds break when
you put in water because water has this
different structure where hydrogen is
slightly positive nothing is like
negative and that's why they're breaks
yeah but if you are not putting this in
water this guy is very strong and they
have very high melting points because
the bond is strong the bond is strong so
let us understand their form of
formation of mgcl2 so if you know the mg
has two extra electrons and CL needs
only one one two three four five six
only one extra is required only one is
required so what will happen but this
guy has two to give so one more seal
will come and they say okay now I will
also take one item from you correct
because this guy is giving to 1 2 3 4 5
6 7
this guy is giving 2 so 1 it will give
here 1 it will give here correct why
because 9 is ready to give 2 electrons
but 1 CL Adam needs only one electron so
to see address will come and say okay
both are satisfied now it will happen as
everything is satisfied so if you see
this it is something like this or a
let's try it first like this mg has
given mg plus 2 charge it as God it has
given 2 electron this 2 electrons is
taken by two chlorine items
yeah withdrawing - correct
so if you see the the thing it has mg
blast - chlorine has minus one charge
actually if you see right one two three
four five six seven and one extra
electron is gone and they are two
chlorine items m GC l will represent
like this please don't put a minus 2
charge here
chlorine has only one one charge minus
one charge and they are two fluorine
items weight is mg has two positive
charge chlorine has one negative charge
and they are two chlorine atoms so it's
mg CL you don't write it like this
mg + 2 CL minus 2 they don't like this
like this this is wrong
CL has only chlorine has only one
negative charge and they have two
chlorine atoms with the factor is they
are two chlorine atoms right and each
chlorine atom has -1 charge
that's why chlorine is minus 1 and they
are 2 kilograms
my name is +2 and there is one magnesium
right we have learnt cations anions and
we have sometimes confused what is
cations with anion so I have a memory
tip for this the memorator taste an ox
there is aux-in there is a red cat if
you can imagine this figure this ox
which is trying to pull this red cat
because this oxygen goes toward the red
object right so the red cat is trying to
chase the red cat so if you can remember
this an ox and red cat you will remember
anion and cation so if you see the
memory tables like this an ox is a node
means oxidation and is a known ox miss
oxidation right red is reduction and cat
is scattered so in cathode red cat
reduction happens anode and ox oxidation
happens
reduction is what gain of electron
oxidation once they have a loss
ephedrine because you have sodium it
will lose the electron it is a positive
charge this is called oxidation giving
positive charge losing electron and
reduction is gaining electrons you have
seal and you get this electron you get
CL minus and you are stable we are
stable both artists even see the reason
why oxidation resistant is happening
because everyone wants to gets be stable
sodium was not stable so it got oxidized
and it became any class it is achieving
chlorine was not stable CL it had one
electron less in the valence shell out
Ramos well and self it took one electron
becomes CL minus and nowadays same don't
think that na class has positive so it
is not stable na class is more stable
than na CL minus is more stable than C
right so don't be confused with the
charge at CR minus so it won't be stable
actually secret - is more stable than
flowing sodium plus is most here in
stable that so it is now the the memory
tip the the ox
blackhawks is chasing the red cat right
so anode means oxidation reduction means
