If an atom has 1 to 3 valence electrons, what will it do? move electrons to a lower shell donate electrons move electrons to a higher shell accept electrons

Respuesta :

donate electrons

Atoms with 3 or fewer electrons tend to form cations and donate the valence electrons electron in this way they became with an external 8 electrons shell in accordance with the octet rule in the formation of compounds

Answer: Option (b) is the correct answer.

Explanation:

When an atom has 1 to 3 valence electrons then it shows that there are excess of electrons present in the outermost shell.

Therefore, in order to attain stability the atom will donate electrons to an electron deficient atom.

For example, valency of aluminium is 3 hence it forms [tex]Al^{3+}[/tex] ions by donating electrons.

Thus, we can conclude that if an atom has 1 to 3 valence electrons then it will donate electrons.
