What is covalent bonding?

Back

Covalent bonding is a type of chemical bond where two atoms share one or more pairs of electrons to fill their outer electron shells.

Front

What do atoms aim to achieve through covalent bonding?

Back

Atoms aim to fill their outer electron shells to achieve stability.

Front

What is an ion?

Back

An ion is an atom or group of atoms that has an electric charge due to the loss or gain of one or more electrons.

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged.

Front

What happens to an atom when it loses electrons?

Back

When an atom loses electrons, it becomes positively charged.

What is the charge of a nitrogen atom that gains 3 electrons?

Back

The charge of a nitrogen atom that gains 3 electrons is -3.

Front

What is the role of electrons in covalent bonds?

Back

Electrons are shared between atoms in covalent bonds to help fill their outer electron shells.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

Why do most atoms have no net charge?

Back

Most atoms have no net charge because they have an equal number of electrons and protons.
