The number of protons plus the number of electrons isn't a recognized figure in chemistry.
The number of protons is the atomic number of an element.
The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons.
The number of protons plus the number of neutrons is the atomic weight of an element.

Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
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.
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.

The number of protons is 30, the number of electrons is 28, the number of neutrons is different for each isotope.
Carbon-12 has 6 protons, 6 neutrons, and 6 electrons. The number of protons determines the element (carbon), the number of neutrons plus protons gives the mass number (12), and in a neutral atom, the number of electrons equals the number of protons.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
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.
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
The number of protons and electrons in the atom. If the number of protons = number of electrons, it is electrically neutral. If number of protons > number of electrons, it is positively charged. If number of protons < number of electrons, it is negatively charged.
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.
The number of protons is 12, the number of electrons is 10, the number of neutrons is different for each isotope.
Chlorine with 17 protons and a -1 charge has 18 electrons. This is because the number of electrons should equal the number of protons (in this case, 17) plus or minus the charge (in this case, -1).
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons)
