Question

please give me answer in details
​

Answer 1

Explanation:

The elements of group 15 generally exhibit -3, +3 and +5 oxidation states. The tendency to exhibit -3 oxidation state decreases as we move down the group due to an increase in the size of the atom and the metallic character. Bismuth hardly forms any compound in oxidation state -3.

Answer 2

Answer:

The elements of group 15 generally exhibit -3, +3 and +5 oxidation states.

Explanation:

All the elements of group 15 have 5 electrons in their outermost orbit. They need only 3 electrons to complete their octet configuration. The octet can be achieved either by gaining 3 electrons or by sharing 3 electrons by means of covalent bonds. As a result, the common negative oxidation state of these elements is -3. As we move down the group, the tendency to exhibit -3 oxidation state decreases. This is due to the increase in atomic size and metallic character.

Group 15 elements also show positive oxidation states of +3 & +5 by forming covalent bonds.
