Arsenic word list, defined

General dictionary meanings, not specific to this puzzle's theme.

ARSENIC /ˈɑːrsənɪk/ · noun
A chemical element (symbol As, atomic number 33), a brittle grey metalloid that is highly poisonous in many of its compounds. It is also used attributively to refer to arsenic trioxide, the compound historically notorious as a poison. Related: poison, toxin, metalloid, element.
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.
ATOMIC /əˈtɒmɪk/ · adjective
Relating to atoms, or to the energy or structure of atoms. More broadly, describing something that is divided into very small, discrete units. Related: nuclear, minute, tiny.
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.
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.
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.
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.
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.
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.
RADIOACTIVE /ˌreɪ.di.oʊˈæk.tɪv/ · adjective
Having unstable atomic nuclei that spontaneously emit ionizing radiation. Informally, extremely exciting, intense, or dangerously attractive.
RADIOACTIVITY /ˌreɪ.di.oʊ.ækˈtɪv.ə.ti/ (US); /ˌreɪ.di.əʊˈæk.tɪv.ə.ti/ (UK) · noun
The spontaneous decay of unstable atomic nuclei, accompanied by the emission of ionizing radiation such as alpha particles, beta particles, or gamma rays. Related: radioactive activity, radioactive decay.
