Chemical Bonding Review

Front

What is an ion?

Back

An ion is an atom that has a different number of electrons than protons, resulting in a net charge. It can be positively charged (cation) or negatively charged (anion).

Front

What type of bond occurs between two or more nonmetals?

Back

Covalent bond.

Front

What charge does an atom have if it loses one electron?

Back

+1.

Front

Why do elements bond with each other?

Back

To become stable by achieving a full outer electron shell.

Front

What type of bond occurs between metals and nonmetals?

Back

Ionic bond.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond formed when two nonmetals share one or more pairs of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom (usually a metal) to another (usually a nonmetal), resulting in the formation of ions.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the difference between an ionic bond and a covalent bond?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between nonmetals.
