Ionic Names and Formulas

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their outer shell, achieving a stable electron configuration.

Front

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.

Front

How do you determine the charge of a monatomic ion?

Back

The charge of a monatomic ion is determined by the number of electrons lost or gained compared to the neutral atom. Metals typically lose electrons and become positively charged, while non-metals gain electrons and become negatively charged.
