- 2Atomic numberNo of protons
- 3Mass numberNo of protons + no of neutrons.

Chemical properties government by number and arrangement of electrons so not affected. - 5Relationship between electrons and protonsNo of electrons = no of protons.
- 6Arrangement of electronsFor stability, should be 2,8,8
- 7What information do groups and periods give us?Group number - how many electrons in outer shell
