The atomic mass of an atom is the sum of the number of protons and neutrons that it has in its nucleus. The number of protons and number of electrons is the same for a neutral atom and either of them can be used to give the atomic number of the atom. Therefore both the number of electrons and the number of electrons determines the atomic number of an atom

The number of protons in an atom of an element determines the atom's atomic number, and the number of electrons determines the atomic number of an element.

the number of protons in an atom of an element determines the atom's (atomic number),and the number of electrons determines the (atomic number )of an element.

the number of electrons in an atom=the no. of protons=the ATOMIC NUMBER .

if you want to calculate the neutrons number for an atom , you can easily make : MASS NUMBER- atomic number

mass number = no. of positive protons and neutral neutrons

 so,,,the atom consists of positive protons and negative electrons (which resemble the atomic number) and the neutral neutrons .

Electons do not make up the atomic number! Only protons and neutrons do.

Both can be filled with atomic number as the amount of protons are the same as the amount of electrons.

The number of protons in an atom of an element determines the atom's atomic number. Each element has a different atomic number, based solely on the number of protons that element has. The number of electrons in an atom determines the charge of the element. Since electrons are negatively charged and protons are positively charged, more electrons than protons in the atom would make the element negatively charged. Therefore, vise versa, less electrons than protons in the atom would make the element positively charged.

The number of protons is the same as the number of electrons usually. The number electrons determines the atomic number.
