What are the characteristic of p-block elements. |
|
Answer» Characteristics of the p-block elements: (i) The p-block elements include metals, non-metals and metalloids. That is, certain elements in p-block are metals, some are non-metals while some others are metalloids. In a group, the metallic character increases in going from top to bottom. In a period, the metallic character decreases in going from top to the bottom. In a period, the metallic character decreases in going from left to right. (ii) The general outer electronic configuration of p-block elements is ns2 np1-6 (iii) The p-block elements enter into chemical combination by losing, gaining or sharing the valence electrons. The noble gas elements do not show any reactivity. This is because the outermost shell in these elements are completely filled (ns2 np6) (iv) The p-block elements mostly form covalent compounds. The halogens, however, from ionic compounds with alkali and alkaline earth metals. |
