Key Concepts

Isotopes

Isotopes are different forms of the same element that have the same number of protons but differing numbers of neutrons. They share chemical properties because their electron configuration (determined by the proton count) is the same, even though their mass numbers differ due to the variation in neutron count.

Atomic Number

The atomic number is a fundamental property of an element that represents the number of protons in its nucleus. This value is unique to each element and determines its chemical behavior, as well as, in a neutral atom, matching the number of electrons.

Mass Number

The mass number of an atom is the total number of protons and neutrons in its nucleus. It provides a measure of the atomic mass and is used to differentiate between isotopes of the same element.

Neutral Atom Electron Count

In a neutral atom, the number of electrons is equal to the number of protons. This balance of positive and negative charges results in an electrically neutral atom, which is a key consideration when determining the overall subatomic particle count.

Calculating Neutron Number

The neutron number in an atom can be determined by subtracting the atomic number (proton count) from the mass number. This calculation is essential for understanding the isotope's nuclear composition and its resulting physical properties.
