- NEUTRON /njuːtrɒn/ · noun
- A subatomic particle with no electric charge and a mass slightly greater than that of a proton. Neutrons are found in the nucleus of an atom and play a key role in nuclear reactions. Related: proton, electron, ion, nucleus.
- ELECTRON /ɪˈlɛktrɒn/ · noun
- A stable subatomic particle with a negative electric charge, found in all atoms and moving around the nucleus. Electrons are the primary carriers of electricity in solids and are responsible for chemical bonding. Related: negatron, subatomic particle, charged particle, beta particle.
- PERIODIC /ˈpɪriədɪk/ · adjective
- Happening or done at regular intervals; recurring at fixed intervals. Occurring or done at regular times. Related: regular, recurring, intermittent, sporadic.
- TABLE /tæbəl/ · noun

- METAL /ˈmɛtəl/ · noun, verb
- A naturally occurring inorganic solid substance with a characteristic high density and a crystalline structure, composed of atoms of a metal element, such as iron, copper, or gold. To cover or coat with a thin layer of metal. Related: metallic, metallically, metallurgy, mineral.
- ALLOY /ˈælɔɪ/ · noun
- A metal made by combining two or more metallic elements, or a metal and a nonmetal, to give greater strength or resistance to corrosion. As a verb, to alloy means to mix or blend metals in this way. Related: mixture, blend, compound, fusion.
- OXIDATION /ˌɒksɪˈdeɪʃən/ · noun
- The process of losing electrons, resulting in the gain of oxygen or the loss of hydrogen, often accompanied by a change in color or the release of heat. Related: corrosion, rusting, decomposition, combustion.
