Palladium word list, defined
General dictionary meanings, not specific to this puzzle's theme.
- PALLADIUM /pəˈleɪdiəm/ · noun
- A chemical element, symbol Pd, atomic number 46, that is a lustrous, corrosion-resistant precious metal used especially in catalysts, electronics, and jewelry. By extension, a palladium is something that protects or provides security. Related: safeguard, protection, shield, defense.
- 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.
- 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.
- 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.
- ORBITAL /ˈɔːbɪtəl/ · adjective; noun
- Relating to an orbit or to the path of one body around another. In physics and chemistry, a noun meaning a region or state associated with an atomic or molecular orbit. Related: orbital, orbiting, revolving, circling.
- CONFIGURATION /kənˌfɪɡjʊˈreɪʃən/ · noun
- An arrangement of parts or elements in a particular form, figure, or combination; the way something is set up or organized. In computing, the specific setup of hardware or software settings. Related: arrangement, layout, setup, formation.
- 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.
