Ionic & Covalent Bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs between a metal and a nonmetal, where electrons are transferred from one atom to another.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond that occurs between two nonmetals, where electrons are shared between the atoms.

What happens to electrons in an ionic bond?

Back

In an ionic bond, the metal atom loses electrons and the nonmetal atom gains those electrons.

What is the octet rule?

Back

The octet rule states that most elements need 8 valence electrons to achieve a stable electron configuration.

What is the charge of a chloride ion (Cl-) after it gains an electron?

Back

The charge of a chloride ion (Cl-) is -1.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and occur between metals and nonmetals, while covalent bonds involve the sharing of electrons and occur between nonmetals.
