Barium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- BARIUM /ˈbɛəriəm/ · noun
- Barium is a soft, silvery-white metallic chemical element with atomic number 56, belonging to the alkaline earth metals group. It is highly reactive and is best known for its insoluble compound barium sulfate, used medically as a contrast agent in X-ray imaging of the digestive tract.
- 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.
- NUCLEUS /ˈnuːkliəs/ · noun
- A nucleus is the central, typically rounded part of an atom or biological cell, containing genetic material and playing a central role in the cell's activity. More broadly, the term refers to a central, fundamental, or defining part of something. Related: core, center, centre, heart.
- PROTON /ˈprəʊtɒn/ (British); /ˈproʊtɑːn/ (American) · noun
- A positively charged subatomic particle found in the nuclei of atoms. In South Asian English, the word can also mean a person who supports a proposal, policy, or candidate. Related: hydrogen-1 nucleus, positively charged baryon, hydrogen nucleus.
- NEUTRON /ˈnjuːtrɒn/ · noun
- A neutral, electrically uncharged subatomic particle found in the nucleus of an atom and having a mass slightly greater than that of a proton.
- 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.
- ISOTOPE /ˈaɪsoʊˌtaʊp/ · noun
- An isotope is one of two or more forms of the same chemical element that have identical numbers of protons but different numbers of neutrons. Isotopes therefore have nearly identical chemical properties but different atomic masses and may differ in stability and radioactivity.
- RADIOACTIVE /ˌreɪ.di.oʊˈæk.tɪv/ · adjective
- Having unstable atomic nuclei that spontaneously emit ionizing radiation. Informally, extremely exciting, intense, or dangerously attractive.
- ALPHA /ˈælfə/ · noun
- The first letter of the Greek alphabet (Α, α). More broadly, the first or most dominant item in a series, or an animal ranked highest in a social hierarchy. Related: beginning, first, leading, dominant.
- BETA /ˈbiːtə/ (British), /ˈbeɪtə/ (US) · noun, adjective
- The second letter of the Greek alphabet (β, β). More broadly, it denotes the second in a series or a preliminary, testing stage of something — as in software released to users for evaluation before final launch. Related: trial, preliminary, draft, prototype.
- GAMMA /ˈɡæmə/ · noun
- The third letter of the Greek alphabet (Γ, γ), used in mathematics, physics, and statistics to denote a third item in a series or specific quantities such as gamma rays, the gamma function, and the gamma distribution. It also denotes the third member of any ordered group.
- DECAY /dɪˈkeɪ/ · verb and noun
- To decay is to rot or decompose through natural processes, or to decline gradually in quality, condition, or strength. As a noun, decay refers to the state or process of rotting, decomposition, or gradual deterioration. Related: rot, decompose, deteriorate, wither.
