Lead word list, defined
- LEAD /lɛd/ · noun, verb
- A heavy, bluish-white metal, highly toxic and malleable. To guide or direct the way for someone or something. Related: guide, direct, head, precede.
- ELEMENT /ˈɛlɪmənt/ · noun
- A fundamental or essential part of something larger; in chemistry and physics, a substance consisting of atoms all with the same atomic number that cannot be broken down into simpler substances by ordinary chemical means. Related: component, constituent, ingredient, factor.
- ATOM /ˈætəm/ · noun
- The smallest unit of an element that retains the chemical properties of that element, consisting of a nucleus of protons and neutrons orbited by electrons. More broadly, the tiniest conceivable particle or amount of something. Related: particle, molecule, unit, speck.
- PROTON /ˈproʊtɑːn/ · noun
- A subatomic particle that has a positive charge and is found in the nucleus of an atom. It is one of the three main components of an atom, along with neutrons and electrons. Related: ion, particle, subatomic particle, nucleon.
- 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.
- SYMBOL /ˈsɪmbəl/ · noun, verb
- A thing that represents or stands for an abstract concept or an idea, or a person or a group of people. To serve as a symbol of something. Related: emblem, icon, logo, representative.

- VALENCE /ˈvæləns/ · noun
- The capacity of an atom or radical to combine with others; the number of electrons an atom loses or gains to form a chemical bond. In chemistry, the valence of an atom is a measure of its combining power. Related: combining power, chemical affinity, electronegativity, oxidation state.
- 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.
- REDUCTION /riːdʌkʃən/ · noun, verb
