Question

Quizplus · Accepted Answer

The atomic number of an element is equal to the number of protons in an atom of that element. This determines the chemical properties of the element and its placement on the periodic table. The number of electrons an atom can gain or lose depends on its position in the periodic table and is influenced by the number of protons. The number of neutrons can vary among atoms of the same element, resulting in different isotopes. The mass of an atom is determined by the number of protons, neutrons, and electrons, but the atomic number specifically refers to the number of protons.
