❁ ATOMIC SIZE :
✍ The distance between the centre of an atom and its outermost orbital is known as atomic size.
✍ Size of an atom is difficult to define since the position of moving electron in their outermost orbit is not clearly defined.
✍ But still the approximation is possible and significant.
✍ Size of the atom decides ionization energy and electron affinity. electron affinity decides electronegativity and electropositivity.
