Question

why s block elements have only two groups in periodic table. explain

Answer 1

Answer:

The s-block elements share electron configurations. s-block elements are the elements found in Group 1 and Group 2 on the periodic table. ... Because they have 2 valence electrons they are less reactive than group 1. Hydrogen is a nonmetal grouped with the alkali metals because it has one electron in its valence shell.

Answer 2

Explanation:

1) Elements in which the last electron enters the s orbital are called s-block elements. Since s-subshell has only one orbital which can accommodate only two electrons, therefore there are only two groups of
