Single Choice

Atoms $$A, B, C$$ occur in the same period and have one, six and seven as valence electrons respectively. The bond between $$A$$ and $$B$$ will be predominantly:

Aionic
Correct Answer
Bpolar covalent
Cnon polar covalent
Ddative

Solution

$$A$$ has valency 1
$$B$$ has valency 6
$$C$$ has valency 7
$$A$$ and $$B$$ belong to the same period. Electronegativity of the elements increases from left to right in the periodic table. Thus, $$A$$ and $$B$$ have a high electronegativity difference. Hence, they form ionic bonds.
E.g., $$Na^+ + S^{2-} \rightarrow Na_2S$$
Hence, the correct option is A.
