Alkali Metals word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- LITHIUM /ˈlɪθiəm/ · noun
- Lithium is the chemical element with the symbol Li and atomic number 3, a soft, silvery alkali metal. The word can also refer to a lithium-ion battery or, in medicine, to lithium salts used as mood stabilizers.
- SODIUM /ˈsoʊdiəm/ (US); /ˈsəʊdiəm/ (UK) · noun
- A soft, silvery-white chemical element of the alkali metals, with the symbol Na and atomic number 11. In nutrition and biology, the term may also refer to sodium ions or sodium present in compounds such as table salt. Related: Na.
- POTASSIUM /pəˈtæsiəm/ (British); /pəˈteɪsiəm/ (American) · noun
- A soft, silvery-white chemical element of the alkali metals, symbol K, with atomic number 19. In living organisms, potassium occurs mainly as the ion K⁺ and is essential for nerve and muscle function. Related: K, potash, kalium.
- RUBIDIUM /ruːˈbɪdiəm/ · noun
- A soft, silvery-white alkali metal with the chemical symbol Rb and atomic number 37. Rubidium is highly reactive, especially with air and water, and is used notably in atomic clocks and specialized research.
- CAESIUM /ˈsiːziəm/ · noun
- A soft, silvery-gold chemical alkali metal, atomic number 55, that is highly reactive and used especially in atomic clocks and photoelectric cells. Related: cesium.
- FRANCIUM /ˈfrænsiəm/ · noun
- A highly radioactive, extremely rare chemical element with atomic number 87, symbol Fr, belonging to the alkali metal group. It is the most unstable of the first 101 elements and exists in nature only in vanishingly small traces.
- ALKALI /ˈælkəlaɪ/ · noun
- A chemical compound that dissolves in water to produce a solution with a pH greater than 7, neutralizing acids; a soluble base such as sodium hydroxide or potassium hydroxide. Related: base, lye, potash, caustic soda.
- METAL /ˈmɛt(ə)l/; British /ˈmet(ə)l/ · noun; also adjective and verb
- A metal is a relatively tough, lustrous, and malleable substance, such as iron, copper, gold, or aluminum, that conducts heat and electricity and is usually lustrous in its pure form. The word also names a genre of popular music characterized by amplified guitars, heavy rhythms, and vocals. Related: alloy, steel, metallic material, metalwork.
- HYDROXIDE /haɪˈdrɔɪksaɪd/ · noun
- A chemical compound containing the hydroxide ion, OH⁻, usually formed with a metal or another positively charged element. In common chemistry usage, a hydroxide is a compound whose solutions can have a basic or alkaline character.
- BASE /beɪs/ · noun, verb, adjective
- The lowest part or foundation of something on which it stands or is built; also, a starting point or underlying support for an idea, activity, or system. Related: foundation, footing, basis, groundwork.
- VALENCE /ˈvæləns/ · noun
- In chemistry, valence is the combining capacity of an atom, determined by the number of electrons it can gain, lose, or share in forming chemical bonds. More generally and in specialized linguistic use, it can refer to attractive quality or to the number and kinds of grammatical elements with which a word can combine. Related: valency, combining capacity, bonding capacity, appeal.
- 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.
