WebSep 9, 2024 · Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. Protons and neutrons have approximately the same mass, about 1.67 × 10 -24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton, as shown in Table 1.2. WebFeb 13, 2024 · Radiation is energy. It can come from unstable atoms that undergo radioactive decay, or it can be produced by machines. Radiation travels from its source in the form of energy waves or energized particles. …

WebApr 1, 2024 · Fusion. Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.
