Question

Which pair of elements would you expect to exhibit the greatest similarity in their physical and chemical properties? Sr, Te Ga, As Rb, I N, P Ti, Ne

Answer 1

Step-by-step explanation:

N and P will have similarity

Electronic configuration of N

2,5

1s²2s²p⁵

Electronic configuration of P

1s²2s²2p⁶3s²3p⁵

Electronic configuration bears similarity.

Both have 5 electrons in their outermost orbits . So they exhibit similarity in their properties. Both belong to the same 15 th group of periodic table.

Sr and Rb too bear much similarity . Both are strongly electro-positive metal , difference in their atomic no being only one.
