Question

An atom $A$ has $3$ electrons in its outermost shell and another atom $B$ has $1$ electrons in its outermost shell.Which can the correct formula for their compound?

• A. $A{B}_3$
• B. $A_{3}B$
• C. $AB$
• D. Bond formation is not possible.

Answer 1

The correct option is D Bond formation is not possible.

Bond formation is not possible.
An atom A has 3 electrons in its outermost shell.
It will lose 3 electrons to form A${}^{3+}$ cation.
Atom B has 1 electrons in its outermost shell.
It will lose 1 electron to form B${}^{+}$ cation. There is no bond formed between two cations.
