Description: There are three isotopes of hydrogen-protium, deuterium, and tritium. Protium contains one proton and no neutrons. Deuterium contains one more neutron than protium, and tritium contains one more neutron than deuterium. For each isotope, give the atomic number, mass number, number of protons/ neutrons/electrons, and full atomic symbol.

There are three isotopes of hydrogen-protium, deuterium, and tritium. Protium contains one proton and no neutrons. Deuterium contains one more neutron than protium, and tritium contains one more neutron than deuterium. For each isotope, give the atomic number, mass number, number of protons/ neutrons/electrons, and full atomic symbol.

Key Concepts

Isotopes

Isotopes are variants of a particular chemical element that have the same number of protons but differ in the number of neutrons. This difference leads to variations in the mass number while the chemical behavior remains largely similar because the electron configuration is the same.

Atomic Number

The atomic number of an element is the number of protons found in the nucleus of its atoms. It is a unique identifier for each element and is critical in determining the element's position in the periodic table and its chemical properties.

Mass Number

The mass number of an atom is the total count of protons and neutrons in its nucleus. This value is used to distinguish between the isotopes of an element as different isotopes have different numbers of neutrons.

Subatomic Particles

Subatomic particles include protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, where protons determine the atomic number and neutrons contribute to the mass number. Electrons orbit the nucleus and are involved in chemical bonding and reactions.

Atomic Symbol

An atomic symbol is a shorthand notation that represents an element, typically including its chemical symbol along with superscripts and subscripts indicating mass number and atomic number, respectively. This notation consolidates key information about an element's identity and its isotopes.
