Question

important properties of s-block elements ...no spams please ​

Answer 1

Answer:

Important properties of S-block Elements are :-

1. The element of group-1(alkali metals) & group -2 (alkaline earth metal)which have ns1 and ns2 outermost electronic configuration belong to the s-block Elements.
2. They are all reactive metals with low ionisation enthalpies.
3. They loss the outer most electron (s) readily to form 1+ ion (in the case of alkali metals) 2+ ion (in the case of alkaline earth metals ).
4. The metalic character and the reactivity increase as we go down to the group .
5. Because of high reactivity they never found pure in nature.
6. The compounds of the S-block elements , with the exception of those lithium and beryllium are predominantly ionic.
7. They are shiny, silvery, good conductors of heat and electricity and lose their valence electrons easily.
8. S-block elements are famous for being ingredients in fireworks.
