Ionic Bonding (HSC SSCE Chemistry): Flashcards

Electron transfer creating ions held by electrostatic forces

Positive ions formed when atoms lose electrons

Negative ions formed when atoms gain electrons

1+ (lose one outer electron)

2+ (lose two outer electrons)

1- (gain one electron)

2- (gain two electrons)

Simplest whole-number ratio of atoms/ions in a compound

Metal name first, then non-metal with '-ide' ending

Ions formed from two or more atoms joined together
