Answer 2

Answer:

The general outer electronic configuration of s block elements is ns(1−2).

Explanation:

• S block elements are elements from Group 1 and Group 2 of the modern periodic table.
• S block elements have a ns (1-2) general electronic configuration.
• The last electron in each of these elements enters the s-orbital of its corresponding outermost shell.
• The s orbital only has one subshell and can only hold two electrons.
• As a result, there are two types of s block elements: those with one electron in their s-subshell (s1) and those with two electrons in their s-subshell (s2).
• The s-block elements with just one electron in their s-orbital are known as alkali metals, however, the s-block elements with two electrons in their s-orbital are known as alkaline earth metals.
