Web8 aug. 2024 · How many protons and neutrons are present in hydrogen atom? For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons. How many neutrons does … Web13 dec. 2024 · Atoms are made of electrons, protons, and neutrons. The number of protons in an atom defines what type of element the atom is. Familiar elements (like oxygen, hydrogen, carbon, or nitrogen) can be mixed together to form more complex things. Two hydrogen and one oxygen makes water. 12 hydrogen, 6 carbon, and 6 oxygen? …
