They have a negative (−1) electric charge. Electrons are placed in shells around the nucleus.
Protons have positive (+1) electric charge, while neutrons are neutral. Even with all the crazy costumes, its hard to keep track of the super-villain activity in Gotham City - especially when you have a shape-shifter like Clayface running about. Protons and neutrons gather in an area at the center of the atom, called the nucleus. Clayface: actor, shape-shifter and criminal. SummaryĪn atom is made up of protons, neutrons, and electrons, which are considered subatomic particles. Another view is that they form a cloud around the nucleus. In a stable atom (not an ion) the number of electrons equals the number of protons in the nucleus.Įlectrons are set in "orbits" or shells around the nucleus. Its relative mass is 5.489*10 −4 amuĮlectrons have a negative (−1) electric charge. The mass of the electron is 9.109*10 −31 kg. (See Neutrons for more information.) ElectronsĮlectrons are considered fundamental or elementary particles. The neutron is made up of one up quark and two down quarks Its relative mass is 1.009 amu, slightly more than that of a proton. The mass of a neutron is 1.675*10 −27 kg. Neutrons act as a form of binding force within the nucleus. Other atoms have the same number or more neutrons as protons in the nucleus. Every element except Hydrogen has at least one neutron in its nucleus. The number of protons in the nucleus of an atom determines the atomic number of the element. Its relative mass is 1.007 amu (atomic mass units). (See Fundamental Particles of Matter for more information.)
It consists of two up quarks and one down quark, fundamental particles. A proton has a positive (+1) electric charge.
