engineering HSC and IIT JEE main and
advanced videos now we are going to do
what is periodic trends in the
properties of elements so before
understanding there let us let me tell
you that there are periodic tests that
are based on when we go according to the
group of any who according to the
periods this kind of change that we
observe is the properties of the
elements will be known as a periodic
times in the properties of elements but
what are the properties of the elements
let us talk about that also
so now we are going to talk about the
properties of the element that it
changes according to the group or
according to the period that is being
followed through so first so for talking
about the first thing that we are going
to talk about then what are the
properties and those properties are
talking about the first one the first
property is atomic size so atomic size
is the property which is nothing but it
is defined as the distance between the
nucleus and the outermost valence shell
containing an electron so that is known
as the atomic number atomic size so this
atomic size or this property of an
element also changes accordingly also
changes according to depend when we come
to a particular group or when we go
through a particular period there is
from left to right so this is the first
property that has enough product n so
document for the next one the next is
nothing but ionic size similar to that
of the atomic size it is nothing but the
difference with the distance between the
nucleus and the outermost electron or
the outermost valence shell of and I
that contains an electron but in case of
the both that they have the differences
because atom is for atomic size is for
an atom by ionic size is for and I am
and that can be cut and also that can be
NN also so mundos the next one the next
properties analyzation and something
again this is the property that has a
trend when it comes to the periodic
table so this also changes with when we
go through left to right or when we go
through up to down before observing a
particular kind of an elements in that
group or in that period so what is
ionization enthalpy it is nothing but
the energy required to remove the
electron from the outermost
or be dolphin Adam so this is known as
ionization that pain we are going to do
it deep analysis or deep theory about
each and every property but let me tell
you that what is actually the puritans
in properties of elements so talking
about the third one the third one we
have open that we have it is known as
electron game enthalpy so electron Nina
the P is nothing that the energy that
please when an electron is been accepted
by an atom or by an ion so the amount of
energy that has been released is nothing
known as a tone gain enthalpy as the
name suggests that the while accepting
or by gaining an electron there will be
an impact machine so that is known as
electron Givens helping and talking
about the last one that is
electronegativity so what is actually a
productivity electronegativity is
nothing but the tendency of an atom to
acquire or to accept an electron from
another atom so that is known as or
accept an electron which is premise to
it so this is known as the electronic
three talking about electronegativity
fluorine is the one which is having a
most on highest electronegativity in the
whole periodic table so therefore this
is electron I agree and this all are the
basically the trends we can see the
trend in this kind of properties of the
element in the periodic table but
talking about the last row that we have
that is it is nothing but the valency
even valency is the one property which
changes maybe when we are talking about
a group or maybe I'm talking the trend
in periods so this are the properties
that we are going to talk about so thank
you friends for watching this video I
hope you have understood that these are
the properties that will change
according to the group or according to
the period when we are looking toward
the hole
series of the elements present in a
particular period or present in
particular coop so thank your friends
for watching this you know I hope you
have liked this video and you share this
with your friends and it's don't forget
to subscribe we get us in thank you so
much
