The general electronic configuration of p-block elements is
ns1
ns2
ns2 np1–6
(n–1)s2 np1–6
p-block element consists of the groups
1 & 2
3 - 12
13 - 17
13 - 18
As we go down the group metallic character
decreases
increases
become constant
become zero
In p-block, non-metals are placed in
upper right part
middle part
lower left part
bottom of the group
Which of the following factor is not responsible for the anamolous behaviour of the first member of each group in a p-block elements
small size
high ionisation enthalpy
outer electronic configuration
absence of d-orbitals
In 13th group Tl+1 ion is more stable than Tl3+ ion due to
high electronegatively
inert pair effect
high ionisation energy
stable electronic configuration
pick the odd man out
In
Pb
Cl
Al
Choose the wrong statement
Some of the p-block elements show negative oxidation states also
Halogens gain two electrons to give a stable halide ion
Inert gases have ns2np6 configuration and hence more stable.
P block elements contains metalloids
Some elements exist in more than one crystalline or molecular forms in the same physical state. This phenomenon is called
Isophorphism
Allotropism
both
none
The elements N, O, F readily forms hydrogen bonds due to their high
ionisation energy
electron affinity
electro negativity
atomic radius
