Diagonals are where most players stall. Once you are down to the last word or two, sweep the diagonals deliberately.
The Periodic Table word list, defined
- 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.
- 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.
- 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.
- PERIOD /ˈpɪəriəd/ (British); /ˈpɪriəd/ (US) · noun
- A period is a punctuation mark consisting of a dot placed after a sentence or at the end of an abbreviation. It can also refer to a distinct span of time, a historical era, or a regularly recurring phase in a process. Related: full stop, point, span, interval.
- GROUP /ɡruːp/ · noun, verb, adjective
- A group is a set of people, animals, or things regarded as a collective, especially people sharing an organization or category; as a verb, to group is to arrange or classify them together. In attributive use, group also means belonging to or characteristic of a collective. Related: cluster, set, collection, team.
- 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.
- REACTIVITY /ˌriːækˈtɪvəti/ · noun
- The quality or degree of being reactive: readiness to respond to stimuli, or, in chemistry, the tendency or ability to undergo chemical change. Related: responsiveness, sensitivity, volatility, excitability.
- 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.
- SHELL /ʃɛl/ · noun, verb
- A shell is a hard or rigid outer covering, especially that of a mollusc, egg, seed, or animal. As a verb, to shell can mean to remove something from its shell, or to fire shells from a weapon or bomb a place with shells. Related: casing, hull, husk, covering.
- 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.
