In ionic bonding, how can atoms get the same number of electrons as a noble gas?

By gaining or losing electrons.

The two types of compounds are ionic and molecular (covalent).

Ionic compounds are formed when atoms transfer electrons, while molecular (covalent) compounds are formed when atoms share electrons.

Atoms that gain electrons get a negative charge.

Atoms become negatively charged ions (anions) when they gain electrons.

Nonmetals tend to form ions with a negative charge.

Nonmetals typically gain electrons to form negatively charged ions (anions).

Molecular compounds are formed when atoms share electrons.

Molecular compounds involve covalent bonding, where electrons are shared between atoms.

Ionic compounds are formed when a metal and a nonmetal bond together.

Ionic compounds result from the transfer of electrons between a metal and a nonmetal.
