- 1AnionWhen non metals gain electrons
- 2CationWhen a metal loses an electron
- 3What is the rule for maximum electrons?2n squared
- 4Charges of ElectronsIf you lose electron you become +
If you gain an electron you become - - 5What makes it hard?The strong attraction of the opposite charged electrons
- 6What gives it a high melting point?Due to the strong bonds
- 7CrystalsHas to do with lattice structure
Generally brittle - 8Non ConductorsWhen its a solid as ions can't move
- 9ConductorsWhen dissolved in liquid as ions can now move
- 10Names of ionsMetals: there is no name change
Anions: cut ending of element and add 'ide'
Eg: Oxygen-Oxide - 11Number on top of element# of protons
- 12Number on bottom of element# of protons and neutrons
- 13What happens to an element in group 14They neither lose or gain electrons as they have a full outer shell
- 14What does it mean to be solubleThe cations and anions attract to the oppositely charged side of the water molecule
- 15Polyatomic ionis when there are more than 2 atoms bonded together such as No3
