Answer:
Four characteristic properties
of p-block elements.
(i) Except F and inert gases,
p-block elements show a number of oxidation states from +n to (n-S) where n is the
number of electrons present in the outermost shell.
(ii) p-block elements have
general outer shell electronic configuration\[n{{s}^{2}}n{{p}^{1-6}}\]. The
number of electrons in penultimate shell is either 2 or 8 or 18.
(iii) Most of the elements are
electronegative. The electronegativity increases in a period and decreases in a
group.
(iv) The p-block elements show
covalency but higher members can show electrovalency also. The highly
electronegative elements can show electrovalency by accepting electrons. Some
members also show coordinate valency.
