a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, leading to variation in atomic mass
containing or relating to a dangerous form of energy produced by nuclear reactions
a type of chemical bond between two atoms involving the sharing of two pairs of electrons, resulting in a stronger and more stable connection than a single bond
defining substances or surfaces that have a strong attraction to water molecules, allowing them to easily absorb or interact with water
characterized by substances or surfaces that repel water molecules, showing little or no affinity for water
a chemical reaction that releases heat energy to its surroundings, typically resulting in a temperature increase
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease
the weighted average mass of an atom of an element, taking into account the masses of all its naturally occurring isotopes
a fundamental unit in chemistry that represents the amount of substance containing as many entities (atoms, molecules) as there are in 12 grams of carbon-12
a laboratory tool used to measure and transfer small volumes of liquid
a tabular arrangement of chemical elements organized based on their atomic number, electron configuration, and recurring chemical properties
the process where calcium or calcium salts accumulate in a tissue, making it hard and rigid
a laboratory method used to determine the concentration of a substance in a solution by gradually adding a reagent of known concentration until a reaction is completed
the process by which microorganisms convert carbohydrates into alcohol, acids, or gases
the measure of how much of a substance is present in a certain volume of solution
a group of atoms bonded together that behaves as a single unit within a molecule
a test that measures the presence, amount, or activity of a specific substance in a sample, often used in scientific and medical research
a state in a chemical reaction where the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products
(chemistry) the process of separating a liquid or solution into its parts by passing electricity through it
to disperse fine particles throughout a fluid so they remain evenly distributed without settling
a tiny, tube-shaped structure made of carbon atoms, with remarkable strength and electrical properties
a phase is a distinct form of matter with uniform chemical and physical properties, separated from other forms by boundaries
to eliminate or neutralize harmful substances
denoting substances with a highly organized molecular structure, akin to crystals
a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase
a type of radioactive decay where a nucleus emits a beta particle (electron or positron) to transform a neutron into a proton or vice versa
a device that turns vapor into liquid by cooling it
weak attractive forces between molecules or atoms, arising from temporary or induced dipoles
a scientist or engineer who specializes in the study and production of metals and alloys, including their properties, processing methods, and applications
the process by which molecules of a substance adhere to the surface of a solid or liquid, forming a thin film or layer
a renewable, alternative fuel made from organic materials such as vegetable oils, animal fats, or recycled cooking grease
