Chemistry Terms -Glossary
1-heat – energy transferred from one system to another by thermal interaction
2-halogens – Group 7 on the Periodic Table and are all non-metals
3-ionization -The breaking up of a compound into separate ions.
4-indicator – a special compound added to solution that changes color depending on the acidity of the solution; different indicators have different colors and effective pH ranges
5-ionic bond – electrostatic attraction between oppositely charged ions
6-inorganic compound – compounds that do not contain carbon, though there are exceptions (see main article)
7-ion – a molecule that has gained or lost one or more electrons
8-inorganic chemistry – a part of chemistry concerned with inorganic compounds
9-insulator – material that resists the flow of electric current
10-IUPAC – International Union of Pure and Applied Chemistry
11-Joule – The SI unit of energy, defined as a newton-meter.
12-jodium – Latin name of the halogen element iodine
13-Kinetic energy – The energy of an object due to its motion.
14-Kelvin – A unit of measure for temperature based upon an absolute scale.
15-Kinetics – A sub-field of chemistry specializing in reaction rates
16-Law of Motion – An object in motion stays in motion; an object at rest stays at rest unless an unbalanced force acts on it.
17-lanthanides – Elements 57 through 71
18-liquid – A state of matter which takes the shape of its container.
19-light – Portion of the electromagnetic spectrum which is visible to the naked eye. Also called “visible light.”
20-London dispersion forces – A weak intermolecular force
