Noble Gases word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- HELIUM /ˈhiːliəm/ · noun
- Helium is a colorless, odorless, tasteless, extremely low-density chemical element and noble gas, with the symbol He and atomic number 2. It occurs naturally in small amounts in the atmosphere and is extracted industrially from underground reserves.
- NEON /ˈniːɒn/ · noun
- A colorless, odorless, inert noble gas that is a minor constituent of the atmosphere and is widely used in brightly glowing signs and tubes. The word is also used attributively for vivid fluorescent colors and the lighting associated with such signs. Related: noble gas, illuminating gas, fluorescent light, bright sign light.
- ARGON /ˈɑːrɡɒn/ · noun
- A colourless, odourless, chemically inert gaseous element (symbol Ar, atomic number 18) that makes up about 0.93% of the Earth's atmosphere and belongs to the group of noble gases. Related: noble gas, inert gas.
- KRYPTON UK /ˈkrɪptɒn/; US /ˈkrɪptɑn/ · noun
- Krypton is a colorless, odorless noble gas and chemical element belonging to group 18 of the periodic table. In science fiction, the term can also denote a fictional radioactive element or the atmosphere of a fictional planet called Krypton.
- XENON /ˈzɛnən/ · noun
- Xenon is a colorless, odorless, chemically inert noble gas belonging to group 18 of the periodic table, with the symbol Xe and atomic number 54. It is used in high-intensity lamps, photographic flashes, and some light sources because it produces a bright, bluish-white light when electrically excited.
- RADON /ˈreɪdɒn/ (British); /ˈreɪdɑːn/ (US) · noun
- A colourless, odourless, radioactive noble gas that occurs naturally in soil and rock and can accumulate in buildings. Exposure to radon is a significant cause of lung cancer, particularly in people who smoke. Related: radioactive gas, radon gas.
- 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 /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.
- 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.
