What 2 parts of an atom give it is mass?
The atomic mass of an element depends on the weight of the protons, neutrons, and electrons (almost negligible) in one mole (6.022 x 10^23 atoms) of the element.
When it loses two electrons to become a calcium ion what is it's new mass?
38 amu EDIT: This answer is INCORRECT. Electrons do not have significant mass.
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
The mass of a neutron is nearly equal to the mass of what other subatomic particle?
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

What is the total mass of an atom having 2 neutrons 2 electrons and 2 protons?
It is about the helium gas. mass number of it is 4.
What does alpha decay do to an atom mass and atomic number?
Reduces the number by 2 and the mass by 4.
What percentage of an atom's mass is caused by the Higgs boson?
About 2% of an atom's mass is caused by the Higgs boson. The rest is due to the effect of the Strong Nuclear Force.
