The number of protons is equal to the number of electrons and the atomic number.
The number of protons is the atomic number.
The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
# protons = atomic number.
The number of protons in the atomic nucleus is equal to atomic number.
The number of protons in an elements nucleus is the same number at the atomic number.
The number of protons in an atom.
The number of protons is equal to atomic number: neon 10 has protons.
atomic number is the number of protons in the atom. mass number is protons and neutrons combined.
It is the same as the number of protons if it is a neutral atom, or the number of protons plus the charge of the ion. The number of protons is the atomic number of the element.
There are 54 protons in the nucleus of xenon. You can find the number of protons of any element on the periodic table by noting the atomic number of the element. The atomic number is the same as the number of protons.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
