blended - pblock

Question 1

what is the highest oxidation state of P-block elements

Answer 1

the group number of the element

Question 2

what is the lowest oxidation state of P-block elements

Answer 2

2 lower than the group number of the element

Question 3

what determines which oxidation state is the most stable

Answer 3

octet expansion and inert pair effect

Question 4

what is octet expansion

Answer 4

the ability of elements to use available d-orbitals so that there are more than 8 electrons in the outer shell

(molecules formed are sometimes called hypervalent)

Question 5

what is the inert pain effect

Answer 5

increasing reluctance, as you move down the group, of the s2 pair of electrons in the bonding level to become involved in bonding.

Question 6

what oxidation states become more stable as you go down group 3

Answer 6

lower

Question 7

what oxidation states become more stable as you go down group 4

Answer 7

lower

Question 8

what oxidation states become more stable as you go down group 5

Answer 8

lower
