What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. Example: NaCl (sodium chloride).

Front

What charge does an anion carry?

Back

An anion carries a negative charge.

Front

What type of bond forms between two metals?

Back

A metallic bond forms between two metals.

Front

How do atoms form an ionic bond?

Back

Atoms form an ionic bond by transferring electrons.

Front

What type of bond is formed when two or more electrons are shared?

Back

A covalent bond is formed when two or more electrons are shared.

Front

What is the charge of a cation?

Back

A cation carries a positive charge.

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

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

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 is a chemical formula?

Back

A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound.
