Question

How can you determine the number of valence electrons in an atom using the Periodic Table?

Answer 1

Determining the number of valence electrons.

Explanation:  

Valence electrons are those electrons that occupy the position in the outermost shell surrounding an atomic nucleus. One can determine the number of valence electrons in an atom with the use of a periodic table. For example, the periodic table consists of rows and columns by identifying the column number of any atom one can determine the number of valence electrons in an element.

For example  

Any element in group 16 has six valence electrons for instance; element oxygen which is 16th group has 6 valence electrons.
