Key Concepts

Atomic Number

The atomic number represents the number of protons in an atom's nucleus and uniquely defines an element, regardless of the number of neutrons. It is a fundamental property that distinguishes one element from another.

Weighted Average Calculation

This concept involves computing the average atomic mass by multiplying each isotope's mass by its relative abundance and summing these values. As a result, the average atomic mass often does not match the mass number of any individual isotope present in nature.

Average Atomic Mass

The atomic mass listed on the periodic table is a weighted average of the masses of all the naturally occurring isotopes of an element. It takes into account the relative abundance of each isotope, meaning it is generally not the mass of any single isotope but an average value.

Isotopes

Isotopes are atoms of the same element that have an equal number of protons but a different number of neutrons, resulting in different mass numbers. They occur naturally in varying proportions and each contributes differently to the overall atomic properties of an element.
