Write four characteristic properties of P- block elements.
The four imnportant characteristic properties of p - block elements are the following
(a) P - Block elements include both metals and non-metals but he number of non - metals is much higher than that of metals, Further, the metallic character incresases from top to bottom within a group and non-metalic character increases from left to right along a period in this block.
(b) their ionisation enthalples are relatively higher as cmpared to s- block elements.
(c) They mostly form covalent compounds.
(d) some of them show more than one (variable) oxidation states in their compound. Their oxidizing character increases from left to right in a period and reducing character increases from top to bottom in a group.
