Atomic Structure

Cards in this deck (7)
- 1Structure of an atom

- 2Atomic numberNo of protons
- 3Mass numberNo of protons + no of neutrons.
The mass number is always greater than the atomic number - 4IsotopesAtoms with the same atomic number but different mass number because the number of neutrons varies.
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
Period - how many shells there will be
