that is called the atomic number or the proton number
they r both correct
i no Bcuz my teacher told me
The number of protons in an atom's nucleus is the Atomic number.
The number of protons in an atom's nucleus determines its chemical identity.
The atomic number of an element accounts for the number of protons in the nucleus of the atom of that element. For example: * Hydrogen atomic number is one. The nucleus of its atom has one proton. * Oxygen atomic number is 8. The nucleus of its atom has 8 protons. * Iron atomic number is 26. The nucleus of its atom has 26 protons. * Lead atomic number is 82. The nucleus of its atom has 82 protons. * Uranium atomic number is 92. The nucleus of its atom has 92 protons.
The atomic number is equal to the number of protons in the nucleus of an atom.
nass number is the number of neutrons plus protons in the nucleus of an atom
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
The number of protons in the nucleus of each atom that has the atomic number.
The atomic number of an atom is equivalent to the number of protons in its nucleus.
the number of protons found in the nucleus of an atom
Is the number of protons in an atom determines its atomic number
