The atomic number is determined by the number of protons, which are located in the nucleus.
The number of protons in the nucleus of an element gives that element its ATOMIC NUMBER.
Protons.The atomic number of an atom is the number of protons in the atom. The identity of an atom is based on its atomic number, so a change in the number of protons mean an atom has turned into a different element. However, an addition or subtraction of neutrons creates different isotopes of an element, and a change in the number of electrons creates an ion of the element.
There is no individual sub-atomic particle that is responsible for the identity of an element. It is the way the electrons, protons and (neutrons) are arranged in an element that gives it it's identity.
The number of protons is unique for every element.Varying the number of neutrons will give you an isotope of the same element.Varying the number of electrons will give you an ion of the same element.
An atomic number goes with a single element notto a combination of elements.
The atomic number on the periodic table is the number of protons for the element.
Atomic Number It is thre position of the atom in the periodic table. It is the number of protons in the neucleud. It is the number of electrons in the neutally charged atoms. Atomic MASS it the total of the protons and neutrons in the atom.

The particle you are describing is an atom of iron. The number of protons in an atom determines its atomic number, which is 26 for iron. The sum of protons and neutrons gives the atomic mass number, which is 56 for this iron atom.
The atomic number for an element corresponds to the number of protons in its nucleus. Fluorine has 9 protons in its nucleus, which gives it an atomic number of 9. This unique number defines fluorine as an element on the periodic table.
An element's atomic number gives its number of protons. Lutetium's atomic number is 71. Thus, it has 71 protons.
