This question is inadequate; an average number of protons and neutrons has no sense.
The number of protons in the known today chemical elements is between 1 and 118.

Mass number - atomic number?
This is the sum of all protons and neutrons in an atom. On the periodic table, it has the average for that element.
What is the number of protons in an average atom of aluminum?
Aluminium has 13 protons in all isotopes.
What is the number of atomic mass in a atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What is an atom called when you have the same numbers of protons as electrons?
On average, in any atom, you will have the same number of electrons and protons.
Mass number - atomic number?
This is the sum of all protons and neutrons in an atom. On the periodic table, it has the average for that element.
What is the number of protons in an average atom of aluminum?
Aluminium has 13 protons in all isotopes.
Number of protons in a an atom of an atom?
The number of protons in an atom is its atomic number.
What is the number of atomic mass in a atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is The atomic weight of an atom reflects the average number of?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How do you get number of protons in a atom?
Atomic number of a atom is same as the number of protons of the same atom
The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
What does the number of protons do to the atom?
The atom identity is given by the number of protons.
What is an atomic number and a mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
