Question

How is the position of an element in the periodic table related to the number of valence electrons?

Answer 1

Position of an element in the periodic table related to the number of valence electrons:

• Based on the number of valence electrons, the elements are arranged in the periodic table.
• The outer shell electrons are the valence electrons. These valence electrons are far from the nucleus.
• In the periodic table across each row or period, the valence electrons increase one by one in group $1-2$ and group $13-18$.
• Elements in the same column or group have the same number of valence electrons.
