Atomic size is the distance between the centre of an atom to the outermost shell , in other words it is the radius of the atom.
atomic size increases down a group since a new subshell is added.
atomic size decreases across a period since an extra electron is added in same subshell increasing effective nuclear charge, and thus nucleus attracts subshell closer decreasing atomic size.
