Question

write the general properties of s and d block elements (four point each)​

Answer 1

Answer:

s block elements

1. Elements in which the last electron enters the s orbital of their respective outermost sheel is called s block elements.

2. Their are 14s - block elements in the periodic table.

3. s sub shell has only 1 orbital which can accommodat only 2 electrons, therefore there are only two groups of s block elements .

4. Elements of and group 1 ( hydrogen and alkali metals) and group 2 (alkaline earth metals) and helium comprises a s block elements

d block elements

1. They are hard , malleable and ductile metals with high melting and boiling point.

2 . They are good Conductor of heat and electricity.

3.They form both ionic and covalent compound.

4. They show variable oxidation states.
