An aluminum atom possesses 2 electrons in its inner electron shell, 8 in the next shell, and 3 in its outermost shell. What is the charge on aluminum when it forms an ion?
A. +2
B. -2
C. +3
D. +8

The charge on aluminum when it forms an ion would be +3

The charge that the atom of an element carries depends on the number of valance electrons in its outermost shell and whether it is more likely to gain or lose electrons to achieve a stable state.

Aluminum atom has 3 valence electrons in its outermost shell. It either gains 5 more or donates the 3 valence electrons in order to achieve an octet state. Since it is easier to donate 3 than gain 5, the atom of aluminum will prefer to donate the 3 valence electrons to become stable.

Thus, the aluminum atom will form an ion by carrying +3 charge.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
