Question

Explain your answer.

14. Element X, whose atoms have an outer-shell electron configuration ns^2np^3, is most likely to react chemically to form ions which have a charge of

(A) +3 (B) + 1 (C) -3 (D) -2

16. The n = 1 shell contains _______ p sub-orbitals. All the other shells contain ________ p sub-orbitals.

A. 3,6 B. 0,3 C. 6,2 D. 3,3

​

Answer 1

14. (C) -3; 16. B. 0, 3

Step-by-step explanation:

14. Ionic charge

X: ns²np³.

The element is three electrons short of having a complete octet.

It is likely to react chemically to add those three electrons and form an X³⁻ ion.

16. Orbitals in subshells

The n = 1 shell contains no p orbitals. All the other shells contain three p orbitals.

The n = 1 shell contains only one s orbital. Every higher shell contains a p subshell, and each p subshell contains three p orbitals.
