Characteristics of s and p block elements p block elements

 Characteristics of s block elements :

• Ionization energy and electronegativity is very less in s block elements 

•Most of the compounds are ionic compounds 

•Loss of  electrons during chemical reaction 

•Oxides and hydroxides are basic in nature

•In s block, first group elements of each period has high reactivity

•Among the period s block elements have high atomic radius

•S block elements shows fixed oxidation state. In s block, first group elements show +1 oxidation state and second  group elements show +2 oxidation state. 

Characteristics of p block elements 

•solid, liquid and gaseous states elements are included in this block. 

•Metals, non metals and meteloids are included in this block. 

•p block elements usually shows highest ionisation energy than s block. elements 18th group element has the highest ionisation energy in each period. 

•The element having the highest electronegativity is in the p block. In each period 17th group element has highest electronegativity.
