उत्तर
| Sr. No. | s-block | p-block |
| 1. | The s-block contains groups 1 and 2. | The p-block contains groups 13 to 18. |
| 2. | All the elements of the s-block are metals. | p-Block elements include metals, nonmetals and metalloids. |
| 3. | s-block elements are placed to the extreme left side in the modern periodic table. | p-block elements are placed to the extreme right side in the modern periodic table. |
| 4. | There is no zig-zag line to separate different types of elements in the s-block of the periodic table. | A zig-zag line can be drawn to separate different types of elements (metals, metalloids and nonmetals) in the p-block of the periodic table. |
