Question

what is the correlation between the valency of an element and its position in the periodic table.​

Answer 1

Answer:

The number of valence electrons increases from left to right in the periodic table. If the number of valence electrons of an element is equal to 4 as that of carbon,the the element would also have same valency that is 4.

Explanation:

The electronic configuration of an element is related to its position on the periodic table. The links are: the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in.The number of valence electrons in an atom is reflected by its position in the periodic table of the elements (see the periodic table in the Figure below). Across each row, or period, of the periodic table, the number of valence electrons in groups 1–2 and 13–18 increases by one from one element to the next.
