Answers

Answered by zahraqamar22

Answer:

Explanation:

When we move from left to right in periodic table valency increases. But after 4, it decreses also. The electrons present in the last shell determine the valency of a particular element. If the number of valence electrons >4: valency = 8 - number of valence electrons.
