How do you get the atomic number?
Atomic number is equal to the number of protons present in an atom. Since an atom is electrically neutral, thus number of protons and number of electrons are equal to make an atom electrically neutral. Atomic number = Number of protons = Number of electrons.
What determines the atomic number of an atom?
The number of protons and neutrons combined to give us the mass number of an atom.
How can the atomic number be determined?
The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. Atomic number = Number of protons. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.
