Basic Sciences - Molecules & Matter

(chemistry) describing a chemical bond formed by atoms sharing pairs of electrons

a particle with a net electric charge due to loss or gain of one or more electrons

(chemistry) relating to or involving ions, which are atoms or molecules with an electric charge

the state of a substance that is without shape and can flow easily

the state of a substance that is neither solid nor liquid

the smallest structure of a substance consisting of a group of atoms

consisting of or relating to molecules, which are groups of atoms bonded together

related to atoms, the smallest units of matter, including their structure, properties, and interactions

(chemistry) the number of protons in the nucleus of an atom, which determines its place on the periodic table

a small particle in an atom with negative charge

a small particle with no charge present in atoms

a small positively charged particle present in atoms

the dense, positively charged core of an atom, made up of protons and neutrons and containing most of the atom's mass

(physics) any of the smallest units that energy or matter consists of, such as electrons, atoms, molecules, etc.

(chemistry) an ion that carries a negative electric charge

(chemistry) an ion that carries a positive electric charge

a link that holds atoms or ions together in any molecule or crystal

a substance that is firm and has a certain shape, not like gas or liquid

(chemistry) a mixture where tiny solid particles float throughout a liquid or gas

the weighted average mass of an atom of an element, taking into account the masses of all its naturally occurring isotopes

the total number of protons and neutrons in the nucleus of an atom

(chemistry) a bond where electrons move freely among many metal atoms, allowing electrical conduction

(chemistry) a weak attraction between a hydrogen atom in one molecule and an electronegative atom like oxygen or nitrogen in another
