- 1What is an ion?An ion is a charged atom.
- 2Atoms that [gain/lose] electrons form negative ions. If atoms [gain/lose] electrons they form positive ions.Atoms that gain electrons form negative ions. If atoms lose electrons they form positive ions.

- 6Isotopes have similar [chemical/physical] properties, but their [chemical/physical] properties, such as density, can differ.Isotopes have similar chemical properties, but their physical properties, such as density, can differ.
