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.
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. ... The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.
