What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed between two ions with opposite charges, typically between a metal and a nonmetal.

Front

Define the Octet Rule.

Back

The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What is the charge of a neutral atom?

Back

The charge of a neutral atom is 0, as the number of protons equals the number of electrons.

Front

What happens to an atom that loses an electron?

Back

An atom that loses an electron becomes positively charged and is called a cation.
