Helium nucleus charge
WebTo calculate the specific charge, we first multiply the charge of one proton by the total number of protons, which in the case of a carbon atom is six. Total charge = 6 ⋅ ( 1.6022 ⋅ 10 − 19 C) = 9.6132 ⋅ 10 − 19 C. Now we multiply the mass of the particles that make up the nucleus by the particle’s number, which in this case is twelve. Helium-4 ( He ) is a stable isotope of the element helium. It is by far the more abundant of the two naturally occurring isotopes of helium, making up about 99.99986% of the helium on Earth. Its nucleus is identical to an alpha particle, and consists of two protons and two neutrons. Alpha decay of … Meer weergeven The helium atom is the second simplest atom (hydrogen is the simplest), but the extra electron introduces a third "body", so the solution to its wave equation becomes a "three-body problem", which has no analytic … Meer weergeven The nucleus of the helium-4 atom is identical to an alpha particle.
