Question

which are the differences in the reactivity of first and second element in the group 15​

Answer 1

Answer:

2nd elementwill be more reactive than first element

Explanation:

as we go down the group electropositivity increases. the effective nucleur charge of the atom also increases and also the no. of shells also increases and so it becomes easy for an atom to loose its valence electrons easily. therefore second element of the group can easily loose electrons than the first one because the distance between its nucleus and valence electron is much and so it is easier for it to loose electron
