Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of one or more valence electrons from one atom (usually a metal) to another atom (usually a nonmetal), resulting in the formation of positive and negative ions that attract each other.

What is a covalent bond?

Back

A covalent bond is a type of chemical bond formed when two nonmetal atoms share one or more pairs of valence electrons.

What charge does a metal atom typically have when it forms an ion?

Back

A metal atom typically has a positive charge when it forms an ion, as it loses one or more electrons.

Front

What charge does a nonmetal atom typically have when it forms an ion?

Back

A nonmetal atom typically has a negative charge when it forms an ion, as it gains one or more electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms are most stable when they have eight electrons in their outer shell, resembling the electron configuration of noble gases.

What happens to an atom when it gains an electron?

Back

When an atom gains an electron, it becomes a negative ion (anion).

Front

What happens to an atom when it loses an electron?

Back

When an atom loses an electron, it becomes a positive ion (cation).

Front

What type of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is a valence electron?

Back

A valence electron is an electron that is found in the outermost shell of an atom and is involved in forming bonds with other atoms.
