The mass of electrons, protons, and neutrons:
electrons 9.10938291*10^-31 kg
protons 1.67262178*10^-27 kg
neutrons 1.6749*10^-27 kg
the mass of electrons is way smaller than both, the mass of protons and neutrons
therefore, 1) the mass of 2 electrons is the smallest
Answer:
Sodium is most reactive metal among these. Sodium is present in group one. It is alkali metal.
Explanation:
Please mark as brainliest
Nuclear Fusion is when two atoms (usually Hydrogen and helium because they are very light and abundant) are smashed together to form heavier elements and in the process releases massive amounts of energy. Nuclear Fission on the other hand is when a heavier atom is split apart at the nucleus and releases large amounts of energy and free neutrons and photons. (in the form of gamma rays)
