Name an element in the fourth period of the periodic table with a total of 4 4p electrons

Beryllium has 4 electrons

For you to find the correct element, begin by looking only at the fourth row of elements on the periodic table, as indicated by the 4 in front of the 4p. This number tells you the level, or shell, in which these electrons will reside.

The "p" block is the column containing six individual columns of elements on the right most side of the table. In this configuration, elements can have from one "p" electron, up to six.

The question is asking for the element containing 4 "p" electrons, so on the fourth row of the "p" block, count out each element until you reach four "4p" electrons.

4p1-Gallium

4p2-Germanium

4p3-Arsenic

4p4-Selenium

Selenium, atomic number 34, is the element in the fourth row containing four "p" electrons.
