Question

Why does overlapping decease with increase in size of atom?

Answer 1

Answer:

The greater attraction draws the electrons closer to the protons decreasing the size of the particle therefore atomic radius decreases. down the groups, atomic radius increases this is because there are more energy levels and therefore a more greater distance between protons and electrons

Answer 2

The greater attraction draws the electrons closer to the protons, decreasing the size of the particle. Therefore, atomic radius decreases. Down the groups, atomic radius increases. This is because there are more energy levels and therefore a greater distance between protons and electrons.
