Question

Metals that donate electrons gain _____ equal to the number of electrons donated.

• A. positive charge
• B. neutral charge
• C. negative charge
• D. none of the above

Answer 1

Answer: (A)

Metals that donate electrons gain positive charge equal to the number of electrons donated, For example, atomic number of aluminium is $13$, so the electronic configuration of $Al$ is $2,8$ and $3$. Aluminium has $3$ electrons in the valence shell; it loses $3$ electrons to form $A{l}^{3+}$
