1. Modern Periodic Table and Periodicity
- The modern periodic table arranges elements in increasing order of atomic numbers.
- The modern periodic table has seven periods and eighteen groups.
- Elements with similar properties appear in the same group because their outer electronic configurations are similar.
2. Classification of Elements
- Noble gases are Group 18 elements with completely filled shells: He, Ne, Ar, Kr, Xe and Rn.
- Noble gases are practically unreactive under normal conditions because they have stable electronic configurations.
- Representative elements include groups 1, 2, 13, 14, 15, 16, 17 and 18.
3. Atomic Size or Atomic Radius
- Atomic size or atomic radius is the distance from the centre of the nucleus to the outermost shell of electrons.
- Atomic radius can be expressed in Angstrom unit or in picometres.
- Å = 10^-8 cm = 10^-10 m.
4. Ionisation Energy and Ionisation Potential
- Ionisation energy is the minimum amount of energy required to remove the most loosely bound electron from an isolated gaseous atom to form a cation.
- Ionisation energy is expressed in kJ/mol or eV/atom.
- Ionisation potential is the same quantity as ionisation energy but expressed in eV.
