| 1. General electronic configuration is ns1-2 | 1. General electronic configuration: ns2 np-1-6 ns2 np -1-6 |
| 2. There are two groups in s-block | 2. There are six groups in p-block. |
| 3. The elements present in this block are all metals. | 3. The elements present in this block are mostly non-metals. |
| 4. They show fixed oxidation state. For example, elements in group 1 show oxidation state of + 1 while those in group 2 show oxidation state of +2. | 4. Most of the members show variable oxidation states i.e. exhibit more than one oxidation state. |
| 5. The compounds are mostly ionic in nature. | 5. The compounds are mostly ionic in nature. |
