a) How does electropositivity of elements get affected as we move: (i) down a group (ii) across a period? b] Which atomic property increases as we move across a period and down a group?

Answer»

Solution :a] Electropositivity of elements (i) INCREASES down a GROUP and (ii) decreases as we move from left to right across a period.
B] The atomic number and hence the number of electrons (and PROTONS) increases both across a period and down a group.
