Iridium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- IRIDIUM /ɪˈrɪdiəm/ · noun
- Iridium is a hard, brittle, silvery-white metallic element of the platinum group, known for its high density, corrosion resistance, and exceptional resistance to extreme temperatures. It occurs in platinum ores and is used in industrial catalysts, high-temperature alloys, electrodes, and some fountain-pen nibs. Related: iridium metal.
- 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.
- PERIODIC British /ˌpɪə.rɪˈɒd.ɪk/; US /ˌpi.əˈrɑː.dɪk/ · adjective
- Occurring at regular intervals or according to a recurring pattern; cyclical. In technical contexts, it can also mean relating to a recurring cycle, especially in mathematics, science, or chemistry. Related: regular, recurrent, recurring, cyclical.
- TABLE /ˈteɪbəl/ · noun and verb
- As a noun, a table is a piece of furniture with a flat top supported by legs, used for working, eating, writing, or supporting objects; it can also mean a chart, list, or organized arrangement of information. As a verb, to table a matter means to postpone consideration of it or set it aside for later discussion. Related: chart, grid, schedule, board.
- 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.
- MASS /mæs/ · noun, verb, adjective
- A mass is a large amount, collection, or body of something. In physics, mass is the quantity of matter in an object; the word can also refer to a large gathering or a religious service. Related: amount, quantity, body, bulk.
- CHEMISTRY /ˈkɛmɪstri/ · noun
- The branch of science concerned with the substances of which matter is composed, their properties, reactions, and the ways in which they interact, combine, and change. It also figuratively denotes a powerful mutual attraction or rapport between people. Related: science of matter, chemical science.
