General property of p-block element
∆ p - block elements include metals , non - metals as well as metalloids .
∆ These elements have smaller atomic radii than s - block elements .
∆ The atomic radius decreases from left to right in a period due to increasing nuclear charge . They have high electronegativities . It is due to their small atomic size , the p - block elements possess higher electron affinities than s - block elements .
∆ Halogens , oxygen , sulphur and phosphorus are reactive elements of p - block elements .
∆ They usually form Covalent compounds . Some of these compounds are ionic also . Some of these elements show variable valency and exist in more than one oxidation state in their compounds .
∆ Few elements viz oxygen , sulphur , phosphorus etc . exhibit allotropy .
∆ They have high value of ionisation energy .Their oxides are acidic in nature .
