Ejaan
Kuis
a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure
polimer
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
isotop
containing or relating to a dangerous form of energy produced by nuclear reactions
radioaktif
a chemical bond where atoms share electrons to form a stable molecule
ikatan kovalen
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
ikatan ganda

hidrofilik
characterized by substances or surfaces that repel water molecules, showing little or no affinity for water
hidrofobik
a chemical reaction that releases heat energy to its surroundings, typically resulting in a temperature increase
reaksi eksotermik
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease

a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase
kromatografi
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
peluruhan beta
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
