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.
we already learned no of protons are equal to no of neutrons
only a sum
2 * Z
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.
Fe 2+ (Iron) has... 26 protons 24 electrons 30 neutrons
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.
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 30, the number of electrons is 28, the number of neutrons is different for each isotope.

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 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.
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.

The number of protons is 12, the number of electrons is 10, the number of neutrons is different for each isotope.
The number of electrons should = the number of protons.
The total number of protons plus the total number of neutrons
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
