Question

explain the changes of atomic size and ionization energy in down the group and along the period in modern periodic table with reason​

Answer 1

Answer:

down the group atomic size increase due to increaase in number of shells.

down the group ionization energy decreases since electrons are far from the nucleus.

along the period atomic size decreases and ionization energyy increase due to more attracctive force of nuclues to outermost electron contained in the same shell.
