ALKALI METAL |
Elements in Column 1, except for Hydrogen |
|
ALKALINE EARTH METAL |
Elements in Column 2. |
|
ANION |
A negatively charged ion. |
|
AVOGARDOS NUMBER |
6.02 X 1023 (one mole of anything) |
|
CARBON DATING |
An indicator of age based on the degeneration of different isotopes of Carbon. |
|
CATION |
A positively charged ion. |
|
CONTROL EXPERIMENT |
[Constant & predictable] samples in an experiment that are compared with samples of interest. |
|
CORE ELECTRON |
The non-valence electrons. These do not participate in chemical bonds. |
|
COVALENT BOND |
Atomic Bonds in which Electrons are shared between atoms. |
|
DIATOMIC |
Molecules that have two like atoms, such as F2. In the case of F2, two covalently bonded halogens share electrons that complete their valence shells. |
|
ELECTRO-NEGATIVITY |
Quantifying the tendency of an atom to draw electrons to itself. On the Table, the more electronegative elements are in the top right corner, and the least are in the bottom left. If the difference is >2, the bond will be ionic. If the difference is <2, the bond will be colvalent |
|
FORMULA UNIT |
The smallest repeating unit of elements in a salt. |
|
HALF REACTION |
equations in which electrons are either reactants or products. Together these make up ReDox reactions. (65) |
|
HALOGEN |
Elements located in column 17 |
|
INORGANIC |
Not carbon based. |
|
ION |
an electrically charged atom |
|
IONIC BOND |
The strong electrical attraction betwen cations and ions. These are non sharing, non covalent bonds |
|
ISOTOPE |
Atoms that have the same number of protons and electrons, but a different number of neutrons. |
|
MAGNETISM |
The nature of substances with have some unpaired electrons that orient themselves in such a way as to create a magnetic/energetic field. |
|
MASS NUMBER |
The total number of neutrons plus protons in the nucleus of an atom. |
|
METAL |
A type of element. The majority of elements (the left 3/4) of table on page 42. |
|
METALIC BOND |
An interaction in which atoms are ionized and share electrons in a "Fluid Sea" This allows metals to be malleable and conduct heat & electricity. |
|
MINERAL |
Inorganic, crystalloid substance. |
|
MOLAR MASS |
Mass, in grams of 1 mol of a given element. |
|
MOLE |
Simply a counting device. Technically the number of carbon atoms in 12g of Carbon12 6.02 X 1023 |
|
NOBLE GAS |
Elements located in column 18. |
|
NOBLE GAS CONFIGURATION |
Complete valence shells that render them un-reactive |
|
NON-METAL |
Elements that are generally gases or brittle solids. (42) |
|
ORGANIC |
Compounds with structures based on carbon framework. |
|
OXIDATION REACTION |
The process of the loss of electrons. |
|
OXIDIZING AGENT |
Things that steal electrons. Not necessarily oxygen. |
|
POLAR BOND |
A type of covalent bond where there is an unequal sharing of electrons which results in one side of the molecule being more positively charged, and one side more negatively. |
|
REDOX REACTION |
Combined REDuction and OXidation half reactions (65) |
|
REDUCING AGENT |
A species that provides electrons. |
|
REDUCTION REACTION |
The process by which electrons are gained. |
|
SALT |
Compound molecules that are formed by the transfer of electrons from one atom to another in order to create an anion and a cation. The strong attraction between them is called an Ionic Bond. Salts must have zero net charge. |
|
SCIENTIFIC NOTATION |
System for managing extremely large or small numbers by assigning powers of 10. |
|
TRANSITION METAL |
Center block of elements in Periodic Table. |
|
VALENCE ELECTRON |
The outermost electrons. These are added to or taken away as the atom try to reach Noble Gas Configuration. |
|
Ionic Bonds form between _______ & _______ Covalent Bonds form between _______ & _______ |
metals & non-metals non-metals & non-metals |
