if you mean 2 valence electrons then it should be calcium because it is an alkaline earth metal and when you calculate the number of neutrons using the number of protons, 20 the atomic number, and the Atomic Mass, 40.078..rounded to 40, you get 20 neutrons.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.
If a neutral atom gains electrons it is called what?
If you mean the charge of an alpha particle, it's +2 since they're made up of 2 protons and 2 neutrons, protons having plus 1 charge, neutrons having 0.
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.
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)

In simple terms, its protons plus its neutrons.
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
The mass number of an atom is the sum of its protons and neutrons. It represents the total number of nuclear particles (protons and neutrons) in the atom's nucleus. The number of protons in an atom determines its element, while the number of neutrons can vary to create different isotopes of the element.
The mass number is the sum of protons + neutrons.

protons plus neutrons = atomic number
To answer the second part of your question, an element with varying neutrons is an isotope, and to determine which isotope it is we have the chemical symbol plus the mass number (ie C-14). Going back to the first part, this question is a bit flawed. Protons are relative to the element itself. The atomic number is equal to the number of protons. So nitrogen will always have 7 protons. Neutrons have no charge (neutron=neutral), so a varying amount of neutrons will not affect the charge. To alter your charge you need to look into the amounts of electrons as relative to the amounts of protons, but that's a different matter.
