(a)
Interpretation:
Among the elements represented by sphere [1], [2] and [3] of the same period, the element with highest
Concept Introduction:
The elements are organized in periodic table on the basis of their electronic configuration. They are put in different groups and periods according to their atomic number. This makes the study of these compounds systematic as elements with same chemical properties fall in the same group.
(b)
Interpretation:
The given elements are represented by sphere [1], [2] and [3] of the same period, the element with largest ionization energy is to be identified.

If false, explain why. (a) The effective nuclear charge Zeff is independent of the number of electrons present in an atom. (b) Electrons in an s-orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge because an electron in an s-orbital can penetrate to the nucleus of the atom. (c) Electrons havingl = 2 are better at shielding than electrons havingl = 1. (d) Zeff for an electron in a p-orbital is lower than for an electron in an s-orbital in the same shellarrow_forward
