What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

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.

How many valence electrons do most atoms need to be stable?

Back

Most atoms need 8 valence electrons to achieve stability, following the octet rule.

What is a polyatomic ion?

Back

A polyatomic ion is a group of two or more atoms that are covalently bonded together and carry a net charge due to the loss or gain of electrons.

Front

What happens to metal atoms in ionic bonding?

Back

Metal atoms tend to lose electrons to achieve a stable electron configuration, forming positively charged ions.

What is the charge of a sodium ion (Na+)?

Back

The charge of a sodium ion (Na+) is +1, indicating it has lost one electron.

Front

What is the charge of a chloride ion (Cl-)?

Back

The charge of a chloride ion (Cl-) is -1, indicating it has gained one electron.

Front

What is the formula for aluminum nitrate?

Back

The formula for aluminum nitrate is Al(NO3)3.

Front

What is 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.

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion that has lost electrons, while an anion is a negatively charged ion that has gained electrons.
