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.

What is the element with charge if needed with 23 protons 28 neutrons and 18 electrons with a net charge of 3 plus?
No element or ion as stated can exist, because if it contains 23 protons and only 18 electrons, its net charge must be 23 - 18 = 5 plus, not 3 plus.
What is the net charge of iron with 26 protons 30 neutrons and 23 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)
The atomic mass is equal to the sum of?
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.
What is the alpha charge?
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.
What is the number of protons plus the number of electrons?
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.

Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
What comprises an element's atomic mass?
In simple terms, its protons plus its neutrons.
What is the charge of an atom if the number of protons is more than the number of neutrons What kind of particle is this called?
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.

How do you calculate the atomic number of the given element?
protons plus neutrons = atomic number

What plus what determines the atomic mass?
protons plus neutrons
