Key Concepts

Isotopes

Isotopes are variants of the same chemical element that have identical numbers of protons but different numbers of neutrons. This difference in neutron count results in different mass numbers while retaining the chemical properties defined by the atomic number.

Atomic Symbol Notation

Atomic symbol notation is a concise representation that includes the element's symbol, its atomic number (usually as a subscript), and its mass number (typically as a superscript). This notation is used to quickly convey the identity and nuclear composition of an atom.

Atomic Structure

Atomic structure refers to the arrangement and composition of an atom, including its protons, neutrons, and electrons. The number of protons, determined by the atomic number, defines the element, while neutrons contribute to the mass number; electrons balance the charge in a neutral atom.

Mass Number

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