We have to name an element in the fourth period of the periodic table with five valence electrons.

The rows in the periodic table are often called the periods. The atomic numbers of elements increase by 1 as we move to right in a period.

The columns in the periodic table are called groups. Elements in the same group have similar chemical properties.
