Technetium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- 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.
- 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.
- 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.
- 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.
- 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.
- RADIATION /ˌreɪ.diˈeɪ.ʃən/ · noun
- The emission or transmission of energy as electromagnetic waves or particles, especially as a potentially harmful form of ionizing radiation. In medicine, the term also refers to treatment using radiant energy, such as X-rays or radiation therapy. Related: emission, rays, irradiation, radioactivity.
- RADIOACTIVE /ˌreɪ.di.oʊˈæk.tɪv/ · adjective
- Having unstable atomic nuclei that spontaneously emit ionizing radiation. Informally, extremely exciting, intense, or dangerously attractive.
- 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.
- ENERGY /ˈɛnərdʒi/ · noun
- The strength and vitality required for sustained physical or mental activity; in physics, the property of matter and radiation that is manifest as a capacity to perform work (such as causing motion or the interaction of molecules). Related: vigor, vitality, stamina, dynamism.
- SPECTRUM /ˈspektrəm/ · noun
- The range of different wavelengths or frequencies of electromagnetic radiation, especially visible light. By extension, the word refers to a continuous range or broad variety of qualities, ideas, emotions, or types of something. Related: range, gamut, scope, span.
- 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.
