Answer:
14. (C) -3; 16. B. 0, 3
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.
[ H₃O⁺] = 10 ^ - pH
[ H₃O⁺ ] = 10 ^ - 7.30
[ H₃O⁺ ] = 5.011 x 10⁻⁸ M
