Question

If an element has 3 valence electrons, what charge will likely form on its ion? Hint: It will lose those electrons. What happens to the charge when it loses 3 electrons?

A, +3
B, -3
C. +5
D, -5

Answer 1

The correct answer to the question is Option A. +3

From the question given above, we were told that the element has 3 valence.

When an element loses an electron, a positive ion is formed.

M —> M⁺ + e

Thus, if the element loses its 3 valence electrons, it will form an ion with a charge of +3

M —> M³⁺ + 3e

Considering the options given in the question above, the correct answer to the question is option A. +3
