A solute that ionizes in solution and conducts electricity. |
| electronegativity |
The measure of how strongly an atom holds its electrons. |
| formula unit |
The basic repeating unit of an ionic solid. |
| free electron theory |
A description of metallic bonding that uses randomly shared electrons to explain the properties of metals. |
| ion |
A charged atom or group of atoms formed by the loss or gain of electrons. |
| ionic bond |
A chemical bond in which electrons are transferred from one atom to another. |
| Lewis dot structure |
A method of representing atoms and ions that uses an element's symbol for the nucleus and inner electrons and a series of dots for the valence electrons. |
| metallic bonds |
A chemical bond in which metal atoms are thought to randomly share their valence electrons. |
| molecule |
A particle made up of two or more atoms chemically joined together; a particle formed by a limited number of atoms bonded covalently; the basic unit of a covalent compound. |
