The atomic number is the number of protons in the nucleus of an atom. It determines the element's identity and its position on the Periodic Table. The atomic number of an element can also help to determine its chemical properties.
The number of protons.
The atomic number of nitrogen is 7, which means it has 7 protons in its nucleus. The number 15 following "nitrogen" typically refers to the total number of protons and neutrons in the nucleus, known as the mass number.

The number of protons.
The atomic number is the number of protons in an atom's nucleus. Given an atomic mass of 201, this information alone does not provide the atomic number as different elements can have the same atomic mass due to isotopes. More specific information about the element is needed to determine the atomic number.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
The atomic number is 2, and the atomic mass is 4 (helium)
