Using the periodic table as a tool,identify the atomic characteristic that would most quickly and efficiently identify any single element.
A)number of shells
B)number of neutrons
C)number of protons and electrons
D)number of neutrons and electrons

Question

Quizplus · Accepted Answer

The number of protons in the nucleus of an atom determines its atomic number and therefore its identity as a particular element. The number of electrons in a neutral atom is the same as the number of protons, hence C is the best choice to identify a single element. The number of shells and the number of neutrons and electrons may vary within the same element due to isotopes and ionization.
