9. Why does the s-block span two groups of elements?

The s-block of the periodic table has 1 orbital

we know that each orbital consists of 2 electrons

and since the periodic table arranges the elements on the basis of their atomic number,

the s-block spans 2 groups.

This is also the reason why the p-block spans 6 groups, d-block spans 10 groups and f-block spans 14 groups

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
