Question

I'll mark as BRAINLIEST..........

Group 15 elements------

~down the group electronegativity decreases...
~ And it is also said that inert pair effect of +3 oxidation state increases and +5 decreases down the group...

+3 oxidation state occurs when there us a heavy nuclear charge on ns^2 electrons but electronegativity decreases down the group ,so explain how +3 oxidation state occurs down the group ...​

Answer 1

Answer:

the group 15 elements are also called pnictogens.because they form poison's.
