Number of protons Equals number of electrons = atomic number The periodic chart tells us that Nitrogen has an atomic number of 7.

Nitrogen has seven protons and seven electrons. The formula is used to calculate the number of neutrons.

Number of neutrons = mass number - atomic number As a result, the number of neutrons in a nitrogen atom is 14-7=7.

Nitrogen has an atomic mass of 14.0067 amu.

The average atomic mass is the product of the isotopes' atomic masses multiplied by their abundance. As a result, the atomic mass is a fractional value.

If an element has three isotopes, then Atomic mass average Is the formula for calculating an element's average atomic mass.

So, the answer is that the nitrogen atom possesses seven protons.

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.

Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3
