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

the correct answer to this question is 2

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
