P-Block - Unit3.3

Question 1

what are the 2 oxidation states of p-block elements

Answer 1

max: group number
lower: group number - 2

Question 2

what causes the lower oxidation state

Answer 2

inert pair effect

Question 3

define the inert pair effect:

Answer 3

= The tendency of S^2 electrons to stay paired (remain inert) and forms the lower oxidation states

Question 4

how does stability of lower oxidation state change down the group

Answer 4

stability of lower oxidation state increases down the group

Question 5

which elements are more able to promote 1s electrons to a vacant p-orbital (increase oxidation state)

Answer 5

elements higher up the group

Question 6

which elements show inert pair effect (and why)

Answer 6

heavier elements show the inert pair effect
- as it requires more energy to promote an S electrons.

Question 7

what is a P block element

Answer 7

an element where the outer electron lies in the p-subshell
