how do the following property vary among alkali metal?
atomic radius
ionisation energy
metallic character
- ATOMIC RADIUS:atomic radius vary in a predictable and explicable manner across the periodic table.for instance the radii generally decrease along each period(row) of the table,from the alkali metal to the noble gas and increases down each group(column).
- IONISATION ENERGY:variation across the period:increase with the increase in the atomic number across the period
- METALLIC CHARACTER:metallic characters appear on left side of the periodic table
