Isotopes are atoms of the same element that have the same atomic number but differ in their mass number. This means that isotopes have the same number of protons in their atomic nuclei but a different number of neutrons. In this article, we will explore the concept of isotopes and how to identify them using the atomic number and mass number of atoms.
What are Isotopes?
Isotopes are atoms of the same element that have the same atomic number but differ in their mass number. The atomic number of an atom is the number of protons present in its atomic nucleus, while the mass number is the total number of protons and neutrons present in the nucleus. Isotopes are important in chemistry because they can have different physical and chemical properties, even though they are atoms of the same element.
Identifying Isotopes
To identify isotopes, we need to look at the atomic number and mass number of the atoms. If two or more atoms have the same atomic number but different mass numbers, they are isotopes of each other. For example, carbon-12 and carbon-14 are isotopes of each other because they have the same atomic number (6) but different mass numbers (12 and 14).
