Diagonals are where most players stall. Once you are down to the last word or two, sweep the diagonals deliberately.
Platinum word list, defined
- PLATINUM /ˈplætɪnəm/ · noun
- A chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, silverish-white transition metal. Related: silver, gold, palladium, osmium.
- 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.
- METAL /ˈmɛtəl/ · noun, verb
- A naturally occurring inorganic solid substance with a characteristic high density and a crystalline structure, composed of atoms of a metal element, such as iron, copper, or gold. To cover or coat with a thin layer of metal. Related: metallic, metallically, metallurgy, mineral.
- TRANSITION /trænzɪʃən/ · noun, verb
- The process or state of changing from one form, situation, or phase to another. A change from one activity to another. Related: change, shift, mutation, alteration.
- CATALYST /ˈkætəlɪst/ · noun
- A substance that increases the rate of a chemical reaction without itself being consumed or permanently changed; more broadly, a person or thing that precipitates an event or change. Related: stimulus, impetus, spark, catalyzer.
- OXIDATION /ˌɒksɪˈdeɪʃən/ · noun
- The process of losing electrons, resulting in the gain of oxygen or the loss of hydrogen, often accompanied by a change in color or the release of heat. Related: corrosion, rusting, decomposition, combustion.
- REDUCTION /riːdʌkʃən/ · noun, verb
- The act of making something smaller or less in amount, degree, or extent. A decrease in size, amount, or degree. Related: diminution, lessening, reduction, diminishment.
- ALLOY /ˈælɔɪ/ · noun
- A metal made by combining two or more metallic elements, or a metal and a nonmetal, to give greater strength or resistance to corrosion. As a verb, to alloy means to mix or blend metals in this way. Related: mixture, blend, compound, fusion.
- 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.
- PROTON /ˈproʊtɑːn/ · noun
- A subatomic particle that has a positive charge and is found in the nucleus of an atom. It is one of the three main components of an atom, along with neutrons and electrons. Related: ion, particle, subatomic particle, nucleon.
- NEUTRON /njuːtrɒn/ · noun
- A subatomic particle with no electric charge and a mass slightly greater than that of a proton. Neutrons are found in the nucleus of an atom and play a key role in nuclear reactions. Related: proton, electron, ion, 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.
