Groupwise Electronic Configurations Video Lecture - Chemistry Class 11 - NEET

hello friends this video on
classification of elements part 10 is
brought to you by example a calm no more
fear from exam before watching this
video please make sure that you have
watched part 1 to part 9 till now what
we have seen we have classified the
elements in groups so if periods where
we have seen that each of these elements
has a particular value of maximum value
of outermost shell and if you see
elements in the period if you see or
they they follow a pattern the valence
electron number increase and then
decrease right now we will classify the
elements pH on groups and element in a
particular group they have particular
properties so the elements are
classified into s block P block D in F
blocking so all these elements you see
this is my s block is my P block this is
D block and this is n so all the
elements in s block has a particular
property they have particular chemical
property in physical wall see Wendy drop
also elements has particular properties
M block elements also has some
properties to D properties and in all
these blocks elements hands properties
which are different and that's the
reason why we classify because now as we
know them as blogger you might have some
property so if we talk about any of
these elements I know that since this
guy's part of s block it will have some
properties you easy to understand them
or you can say it is easy to understand
the property of five blocks then easy to
understand or even buy the property of
hundred twenty odd elements
correct this is as good as dividing the
students in different class for example
in this school let suppose they are 120
students right so used to enter the
property for example height age or let's
suppose our subjects they study
subjects they study and let suppose
three three properties we talk about
three properties which we either
intentionally three profits in the
students it is high in and subject to
study so for EE student is difficult to
understand or remember also so what we
can do we can divide this into class one
students plus two plus three plus four
in class I so you see that all the
students were in class one there a is
something seven to eight years passed
away is something eight to nine years
like like that this is my into ten years
10 to 11 years 11 into a little high
dollar we'll say approximately we're not
on it wasn't sure they are some
deviation also you can say this guys are
three field these are 3.5 grade this is
four feet this 4.5 is five me like that
because either height also you can see
that these students have particular
height so it also we can see their class
one students study social science class
by students generally study physics all
those kind of thing we can be so here if
you know that a particular student let's
suppose particulars you might know him
here is a class one I can give a fair
understanding of the property of relate
that is he must be of this age group he
must be having this much ID or he must
be studying these subjects similarly
here there are so many elements
difficult to remember the property of
all that event so we divided the groups
so even if I say that this particular
element belongs to s gone I have vague
understanding that this property this
particular element will have these all
physical properties correct a very
practical comparison on these elements
in the real life
so these blocks are nothing but the
different class where you group this
elements in sharing
so let's and now understand us from the
electronic engage in itself we can tell
that which block in the laundry and how
do you say the outer block will tell you
which lock launch - example I have these
elements and please note here by the
numbers 1 s 2 s 2 P 3 years 3 4 s 4 d 4p
3 s this is the increasing order of
suction energy right increasing energy
or this time so for example if I am
Telling my s block elements right so
hydrogen the outermost electron is this
guy right it is in which Gong s soybean
desk la helium the outermost electrons 1
s assumption so it will also be has
block he lithium will see lithium the
outermost electron is this guy it is in
s subshell beryllium outermost electron
ISM exception so these four are s naught
Y the outermost electron ism S sub C
correct let's see this guy boron boron
outermost is 1 1 is in 2 P so it is P
block XE carbon-carbon all too much
liquid is a key block similarly nitrogen
also last is in P block oxygen fluorine
neon the outermost electron is in P
block so they are wrong right let's see
sodium sodium out Rose neutrons in s
block correct magnesium order of
electrons in s block so sodium and
magnesium are again s there we'll see
elbonian
aluminum Wouter most electron is in T
block this game CCL boolean silicon also
Autobots in P block phosphorus also
Automotion
P block chlorine also P block
argon also people so all these elements
if you see R P know why the outermost
electron is in FIBA let's start with the
next element potassium potassium this
guy's out
electron and it isn't s-block calcium or
was it produced this guy also it has
blocked this way also s block correct
see the next elements scandium this guy
out of oxygen D block so scanning if we
come continue tightening D block right
all these elements if you see so from
here if you see anybody still this zinc
the ultra Moses in D block so these are
all D block elements next if you see the
outermost layman for these elements are
in people right from here to here
Krypton these are all people honorable
correct so if you see this guy this day
outermost is an S block this guy almost
an S block so this guy to write our be
in esse there again s block sorry and
then again if you see these elements on
here today the outer bus is in D block
so they are also D block so these
elements if you see the last power to
Moses it P block so it evade them you
know hope with this you understood how
to classify elements which block it
belongs to base our electronic integer
decide the electronic generation the
outermost electron is in which sub shell
is SP or deception that will determine
which belong in last thank you visit
