Isotope
Elements with the save atomic number but different mass numbers
1 of 24
Ionic bonding
Making an atom stable by transferring electrons
2 of 24
Do metals gain or lose electrons during ionic bonding?
Lose - Forms positive ion
3 of 24
Do non metals gain or lose electrons during ionic bonding?
Gain - Forms negative ion
4 of 24
Giant ionic lattice
When positive ions have a strong electrostatic attraction to negative ions so exist as solids
5 of 24
Covalent bonding
When non metals share electron pairs between atoms
6 of 24
Group number
The number of electrons in the outer shell of the atom
7 of 24
Period number
The amount of occupied shells the atom has
8 of 24
Oxidation
When electrons are lost
9 of 24

Catalysts
16 of 24
Thermal decompostion
When a metal carbonate is broken down by heat to form a metal oxide and carbon dioxide
17 of 24
Precipitation reaction
When two solutions react to from a chemical that does not dissolve
18 of 24
Metallic bond
a strong electrostatic force of attraction between positive metal ions and delocalised electrons
19 of 24
Why does a metal conduct electricity?
The delocalised electrons can move easily
