What is Atomic Number?
The number of protons in an atom is called the Atomic Number of an element. We know that there are various elements and observing all the properties of all the elements individually is tedious work. So we arrange various elements into some group that resembles similar properties. These atoms are arranged on their atomic number. It is the number of protons that any atom has and it is denoted by “Z”.
Atomic Number of Some Common Elements
The atomic numbers of some common elements are discussed below in the table:
Elements | Atomic Number |
---|---|
Hydrogen | 1 |
Helium | 2 |
Carbon | 6 |
Nitrogen | 7 |
Oxygen | 8 |
Chlorine | 17 |

What is Atom?
Atoms are tiny particles that comprise all the things in the known universe. Atoms of an element are responsible for all chemical reactions occurring in nature. We know that atoms are made up of three fundamental particles namely,
- Electrons
- Protons
- Neutrons
These particles are also called subatomic particles as they are found inside atoms. An atom is the basic building block of matter and all the thing around us is made up of combing atoms in different proportions. Let’s learn more about Atom, its constituents, and its structure in detail in this article.
