Diagram of helium atom
WebApr 6, 2024 · The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate … WebWe know that the atomic number of helium is 2 and the atomic mass number is about 4. Neutron = 4 – 2 = 2. Therefore, a helium atom has two neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.
