Atomic size increases down a group of the periodic table. Explain.

Give reason Atomic size decreases across a period but increases down a group of the periodic table

How dould you account for the following : The stability of +5 oxidation state decreases down the group 15 of the periodic table.

In general, the properties that decrease and increase down a group in the periodic table, respectively, are :

Ionisation energy increases on moving down a group in the periodic table.

Atomic size decreases in a ___________of the periodic table as the atomic number increases from left to right. (group/period)

Describe the trend of atomic size along a period and a group in the periodic table.

What happens to number of valence electrons in atoms of elements as we go down a group of the periodic table ?

What is meant by a group in the periodic table?

Assertion: Electron gain enthalpy always becomes less negative as we go down a group in Modern periodic table. Reason: The size of the atom increase on going down the group in Modern periodic table and the added electron would be farther from the nucleus.
