The atomic number is the number of protons in the nucleus of an atom, while the Atomic Mass is the total mass of the nucleus (both protons and neutrons)
All atoms have an appropriate atomic number. An atomic number can be determined by counting how many protons are inside of the atoms' nucleus.
The atomic number of an element is determined by the number of protons in an element.
the number of protons
It determines the mass of the substance per unit volume.
That is the element's mean atomic mass. It's the average atomic mass of the element as found in nature, taking into account how abundant each isotope of the element is in nature. The number of protons in an atom determines what element it is, but not all atoms of many elements have the same number of neutrons in nature. The total number of protons and neutrons determines which isotope of the element it is, and almost all of an atom's mass is in its protons and neutrons. Atomic mass is measured in atomic mass units (amu). One atomic mass unit is equal to one twelfth of the mass of a carbon-12 atom in its ground state. That is approximately 1.660539 yoctograms (a yoctogram is a trillionth of a trillionth of a gram).
Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element. For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus. For a full summary see the link for the periodic table.
The atomic number is the number of protons in a nucleus.
the atomic number represents the number of protons in an elements atoms

The number of protons (aka atomic number) determines the element or substance.
The number of protons.
The atomic number is the number of protons in an atom.
Electronegativity of each atom is what determines the electron distribution of a bond. The electronegativity of an atom affects its distance in its valence electrons and its atomic number.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
Atomic Number
Yes. The number of protons is what determines atomic number.
The atomic number is equal to the number of protons in a chemical element.
atomic number
The number of protons.
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
