Key Concepts

Isotopes

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. This difference in neutron count results in varying mass numbers for each isotope, yet they share identical chemical properties because they have the same atomic number.

Atomic Number

The atomic number is a fundamental property of an element, representing the number of protons in the nucleus of an atom. It uniquely identifies the element and determines its position in the periodic table.

Mass Number

The mass number is the total count of protons and neutrons in an atom’s nucleus. It is used to describe the isotope of an element and is crucial for understanding differences between isotopes of the same element.

Protons

Protons are positively charged particles found within the nucleus of an atom. The number of protons defines the atomic number and, consequently, the identity of the element.

Neutrons

Neutrons are neutral subatomic particles located in the nucleus alongside protons. Their number can vary among isotopes of an element, affecting the mass number and the atomic mass while leaving the chemical properties unchanged.

Electrons

Electrons are negatively charged particles that orbit the nucleus of an atom. In a neutral atom, the number of electrons is equal to the number of protons, balancing the electric charge, and they play a key role in chemical bonding and reactions.
