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 of an atom is determined by the number of protons it has.
The atomic number of an atom is the number of protons in its nucleus.
The number of protons is the atomic number.
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 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.
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 of an atom is determined by the number of protons it has.
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.
Atomic number is the number of protons in a neutral atom
The atomic number of an atom is equivalent to the number of protons in its nucleus.
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.
The number of protons is the atomic number.
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
Atomic number = number of protons as well as the number of electrons in an atom.
