Boron properties & use (Part - 11) - p Block Elements, Chemistry Video Lecture - Class 11

hello friends this video on P block
elements part 11 is brought to you by
exam fear calm no more fear from exam
study the board Nam we have to be a lot
about the chemical and physical
properties of these elements so born is
the first member of his thirty elements
there is no only nonmetal in this group
you see has I met with otherwise where
metals boron properties are different as
compared to other elements in the image
because of small size and high electron
mobility and this is true for all groups
the first the head elements are
different from the remaining elements in
them similarly they have a different
property and you compare board with
Emery paper it has the in relationship
with the silicon but I tried to the
boran's are electron deficient we have
seen that BH 3 law and does they behave
as levers as it suitable you see this
boron has 6 electrons and behaves as the
device s it mainly offers an autobody
guess it we talked about this s 3 be
ugly
borax and cut might try to be you Jenny
to be 407 or aim is to in this is a test
and the abundance SPD less will talk
what about this there are two isotopes
for more boron we have discussed this
also and there are two other crops of
bore one that is an address this is an
address
this is crystalline and we have shown
that this is literally unreacted this is
reactive blocks we eat it right this is
unreacted let's talk about the physical
properties of the bulan is a very hard
solid next diamond after diamond world
is the next hard solid and why it is
hard because it has three dimensional
structure and that's why it is very hard
we talked about this boron is hard to
the other structure right and this guy
is an ISO hetero structure it's very
hard and because the of the structure it
is not only hard has very high been
taken qualify all these same things are
linked actually and therefore electrons
of more only she won't study in this
class
plus it has very low electrical contact
because if you see is all very tightly
coupled or this item and there is no
free electrons for electrical conduction
this shape only can see that it is very
very hard and very high medical
qualified in the electrical field
because I mean also has significant
dysfunction they also have time and also
have a similar property it's talked
about the uses of boron it is used in
the breast was the coolest man in the
army but they wear this it is used in
the aircraft because very hard it is use
the nuclear reactor to control the
speeds electron it is used to create he
placed in glass the glass is she using
lamps the test tubes now they have
weight from the boron because they can
resist hit heat view the normal glass
which used in a house is a crack they
are also used to create steam and a
scratch resistant coating all this is
the utensils and items you see in the
market one of them have a scratch
resistant coating and this has done
using because bone is very hard board is
also used to prepare any septics
it is also using steel duster to prepare
a hardened because the the critical
quality of boron is hardened right
that's why it is used in most of the
place is used in the bulletproof in dust
bulletproof industry because it's hard
nuclear reactor we trace in glass all
this flash distance protein and the most
critical thing is the semiconductor it
is also used to play semiconductors in
fact silicon is more widely used to
create semiconductor because silicon is
cheaply available in the market but
morning also used sometimes thank you
visit exam viacom to watch free' it
should be should be dues try 3 online
tests get the best quality so demetrius
study from the best tutors and mentors
