Einsteinium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- EINSTEINIUM /ˌaɪnˈstaɪniəm/ · noun
- A synthetic radioactive metallic chemical element with atomic number 99 and symbol Es, belonging to the actinide series. Related: element 99.
- 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.
- NUCLEAR /ˈnjuː.klɪər/ (British); /ˈnuː.klɚ/ (US) · adjective; informal noun
- Relating to the nucleus of an atom or to energy and weapons produced through nuclear reactions. In figurative use, it means central, fundamental, or concentrated around a core. Related: atomic, radioactive, thermonuclear, radiological.
- 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.
- 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.
- SYMBOL /ˈsɪmbəl/ · noun
- A character, mark, object, or other sign used to represent something else, such as a letter, number, emblem, or religious sign. Related: sign, emblem, mark, token.
- RADIOACTIVE /ˌreɪ.di.oʊˈæk.tɪv/ · adjective
- Having unstable atomic nuclei that spontaneously emit ionizing radiation. Informally, extremely exciting, intense, or dangerously attractive.
