• An atom is composed of two main parts.
• Nucleus- It is the central, heavy part of the atom and contains neutrons and protons.
• Extra nuclear part- It consists of electrons revolving around the nucleus in fixed circular paths called orbits.
• The number of protons present in the atom is known as the atomic number of the element.
• The atomic number of any element is denoted by the letter Z.
• For example, the Hydrogen(H) atom has one proton and its atomic number is 1.

Hence, the correct answer is the atomic number.
