Metal Non Metal Reaction - Metal & Non Metals, Chemistry CBSE Video Lecture - Class 10

hello friends this video on metal and
nonmetal party lemon is brought to you
by example calm no more fear from exam
before watching this video please make
sure that you have watched part 1 - part
10 so till now we have done the action
on metal with something the action of
nonmetal is something we have done
reaction of metal with metal aza
but we have not done reaction of metal
with non material what will happen if
you react method comment let's see so
when a metal and nonmetal react transfer
of electron takes place from metal
denominator why because this guy you see
metal is ready to be of electron metal
wants to give electron right and
nonmetal always wants to take this
electric so if you see this electron is
common here metal always wants to give
this electron and nonmetal always wanted
because amber sodium will try to give
electron to become na plus and chlorine
will try to take that electron to become
CL minus and the other stable state of
sodium and chlorine and then they will
be form compound con le ciel correct so
why they do like this well explained may
be in the next chapters where we will
explain the atomic structure and the
valence electron the shells where will
tell why this metal has a tendency to
read electron and nonmetals has a
density gate lengths will explain maybe
in the next chapter next chapters yeah
the compound formed in this manner by
the transfer of electron please know the
transfer of electron there is no
shearing this transfer electron from
metal nor middle are called ionic
compounds or electrovalent compounds
both are same they are ionic or
electrovalent compounds where actually
the transfer of electron happens and
this morning that is created ionic
compounds have strong electrostatic
force of attraction between the positive
and negative they are very strong force
and that's why they have high melting in
boiling finally we'll explain that also
ionic compounds have very strong
the attraction between the positive and
negative ions so before we understand
the ionic thing will it explains how the
NaCl is formed let's understand it cell
thing if you see this metals we are more
interested in suppose sodium sodium has
a double number 11 that means it has
this key elements L we have largest a
very brief in this previous classes and
we'll learn more in the next class but
this understand is 11 so it has 2 8 1 as
the number of electrons in the cell the
K shell will have 2 L will have 8 M will
have 1
this M is 1 it it see generally eight or
zero is the stable state right it should
have the formula s or the font is the
outermost outermost shell should be
filled to be stable okay that is the
funda of all the reaction the outermost
shell should be filled to be stable so
in this case if you see M has the
maximum quantity of 8 l has the maximum
quantity of 8 K has 2 now in this case
this guy also for sodium to become
stable it has to either get several
electron because 8 is the requirement or
you lose this guy also you lose this guy
this shell is gone the next cell is this
38 so sodium has two option either to
get 7 electron or to lose one later
Jaynee 7 electron is difficult this
world is very cruel nobody will give my
electron team why will other elements
see the element we hear just like human
beings right so sodium knows that
gaining 7 electron for him is very very
difficult nobody will give him 7
electrons but losing one electron is
easy for him because anyway is nothing
he can lose that right so for you to
lose thing is
easy to gain but to gain is difficult
for example money so for you to spend
money in a shop or in a mall is easier
than to earn money same thing is the
electron-electron is like money for this
Adams but sodium knows that if you can
this lose one extra money which he has
because one one extra money is calling
him discomfort is not be in stable he is
not is not getting sleep
maybe so he was not mean sleep because
the one extra electron it will give the
electron because he has to either get
seven extra electron to get the complete
stability light or has to lose one extra
electron to get still it in life so
bedridden prefer okay let we lose the
extra electron and then you see sodium
has the tendency of losing one extra
later but if you see elements like
chlorine if you see chlorine chlorine
has seven elements in the outermost cell
so he has two options either to give
seven to give seven electrons to someone
or to gain one electron from someone
glory will not like to give seven
because they almost done almost he has
filled up outermost just in need of one
electron right one electron that means
it may come it will be complete it will
be happy in life and it will not give
the cell later on Bashir's earn for a
period of time so what will do is you
try to get one electron somewhere the
moment sodium comes and sodium is ready
to give one electron and sodium becomes
na plus this guy chlorine will take this
electron chlorine will take this
electron and will become Cl minus and
this guy is stable this get stable long
they the stable states right
these guys are stable sodium is happy
with the giving one electron this is not
having a by giving one lectroid is not
having this is outermost will have eight
now does happy
chlorine will get eight it will be happy
so that's the reason why the reaction
happens we will study more in detail
when you study the periodic table well
this study why sodium or why you know
what potassium calcium why things
ambition is more reactive
even if they have one one elements now
Thomas L so those kind of things will
study the next class right and if you
see argon right this guy or neon helium
the outermost cells are all complete
they are this guy needs to he has two
elements electrons this guy needs eight
electrons guy has a this guy Arthur
needs h electrons there has eight and
that's why they are pretty stable in
life they have their they have reached
the calm state they are called st.
didn't see that's st. right they have
stable in life you don't react even if
you pass HCl hydrochloric acid or
anything they won't react they are react
less they are stable life they don't
they don't care they don't react but
these metals like sodium and all since
they have only one extra they just lose
it to become stable
this guy chlorine they have only you
need only one they react more sulphur it
needs two extra it react little less
phosphorus needs three extra it reacts
even less right and if you see in the
case of carbon as I told carbon has four
in the outermost shell so carbon can
either get fourth or can take fourth
it's 50/50 sometimes come and take for
some name carbon so that's why the
carbon forms covalent different kind of
bond will covalent bond because it will
it is neither willing to give for an
electron and nobody is giving to him
nobody is willing to give for electrons
right because he's saying no I've got
four I make it four so the kaaba is a
crisis state and that's why carbon has a
unique properties we learn that in the
next chapter we will discuss more about
carbons but this is how the importance
of electrons sail shell in determining
the reactivity of a metal and nonmetal
hope you understand this part why
rhodium is ready to give electron and
chlorine is ready to take a light thank
