Webb5 apr. 2024 · Protons are found in the nucleus of the atom – the tiny, extremely dense region at the center of the atom. Protons have a positive electrical charge of one (1+) and a mass of about 1 atomic mass unit (1 amu). Together with neutrons, they make up virtually all of the mass of an atom.

Webb29 nov. 2024 · Electrons are tiny compared to protons and neutrons, over 1,800 times smaller than either a proton or a neutron. Electrons are about 0.054\% as massive as neutrons, according to Jefferson Lab. What is smallest subatomic particle? Quarks represent the smallest known subatomic particles. The electron ( e or β ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is … Visa mer Discovery of effect of electric force The ancient Greeks noticed that amber attracted small objects when rubbed with fur.

Webb2 okt. 2024 · My teacher said that the smallest atom is the helium atom, but I think that the smallest atom is the hydrogen atom. It has a single electron and a single proton, whereas the helium atom has a pair of electrons, a pair of neutrons, and a pair of protons, which obviously occupy more space than the hydrogen atom.
