No, atomic number (z) is always bigger or at least equal to mass number (m).
(If there were NO neutrons (n=0): z=p=m-n=m-0=m , ie. Hydrogen with p=1, n=0, z=m)
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
The atomic number is the number of protons in the nucleus of an atom. In electrically neutral atoms, the number is also equal to the amount of electrons orbiting around the nucleus of the atom. The higher the atomic number the heavier the atom. The atomic number of silver is 47 and therefore number of protons/electrons is 47. It has 67 neutrons.
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
The atomic number of an atom is the number of protons in its nucleus.
The atomic number of an atom is determined by the number of protons it has.
The atomic symbols in a modern periodic table are usually arranged so that, from left to right, each atom has an atomic number higher by 1 than the atom immediately to the left, and the first atom in a period has an atomic number higher by 1 than the rightmost atom in the period immediately above.

The atomic number is the number of _____ an atom
The atomic number is the number of protons in the nucleus of an atom. In electrically neutral atoms, the number is also equal to the amount of electrons orbiting around the nucleus of the atom. The higher the atomic number the heavier the atom. The atomic number of silver is 47 and therefore number of protons/electrons is 47. It has 67 neutrons.

The atomic number of an atom is the number of protons in its nucleus.
The atomic number of an atom is the number of protons in its nucleus.
The number of neutrons in an atom can affect the atomic mass of an atom.
Atomic number is the number of protons in a neutral atom
It is equal to the no. of electrons in the atom. It is called the atomic number.
An atom's atomic number is the number of protons within the single atom of an element
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.
