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.
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
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.
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.

Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
The number of protons is 30, the number of electrons is 28, the number of neutrons is different for each isotope.
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.
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
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).
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
