Question:

Name an element in the fourth period (row) of the periodic table with full s and p sublevels.

Periodic Table:

The periodic table comes from the word period. The properties (physical and chemical) of the elements had played an important role to Mendeleev (Father of the periodic table) to form the periodic table. These have regular variation which helps to put them in a group or period.

Answer and Explanation: 1


The periods are shown from right to left on going horizontally in the periodic table.


The 4th period has a number of elements including s-block, p, block and d-block. The first element of this row or period is K (potassium). The K has 19 electrons and it is represented as:

{eq}{\rm{K - 1}}{{\rm{s}}^{\rm{2}}}{\rm{2}}{{\rm{s}}^{\rm{2}}}{\rm{2}}{{\rm{p}}^6}{\rm{3}}{{\rm{s}}^2}{\rm{3}}{{\rm{p}}^6}{\rm{4}}{{\rm{s}}^1} {/eq}
