State the general electronic configuration of p-block elements. Which factors largely governs the properties of p-block elements ? |
|
Answer» Solution :The general electronic configuration of p-block element is `ns_2 np^(1-6)`. Except HELIUM (He) which has `1s^(2)` configuration. The properties of p-block elements are influenced by : (i) Atomic SIZE (ii) Ionisation enthalpy (iii) ELECTRON gain enthalpy (iv) Electronegativity (v) Absence of d-orbitals in second period elements and PRESENCE of d or d and f-orbitals in HEAVIER elements. The presence of all the three types of elements, metals, metalloids and non-metals bring diversification in chemistry of these elements. |
