|
alkali metal
|
Any metal in group 1A of the periodic table
(Lithium, Sodium, Potassium, Rubidium, Ceslum, Francium) |
|
|
alkaline earth metal
|
Any metal in group 2A of the periodic table
(Berylium, Magnesium, Calcium, Strontium, Barium, Radium) |
|
|
anion
|
any atom or group of atoms with a negative charge
|
|
|
atomic radius
|
one-half the distance betweent he nuclei of two atoms of the same element when the atoms are joined
|
|
|
cation
|
any atom or group of atoms with a positive charge
|
|
|
electronegativity
|
the ability of an atom to attract electrons when the atom is in a compound
|
|
|
halogen
|
a nonmetal in group 7A of the periodic table
(Fluorine, Chlorine, Bromine, and Iodine) |
|
|
inner transition metal
|
an element in the ianthanide or actinide series; the highest occupied S subleve and nearby F sublevel of its atoms generally contain electrons; also called inner transition element
|
|
|
ion
|
an atom or group of atoms that has a positive or negative charge
|
|
|
ionization energy
|
the energy required to remove an electon from an atom in its gaseous state
|
|
|
metalloids
|
an element that tends to have properties that are similar to those of metals and nonmetals
|
|
|
metals
|
one of a class of elements that are good conductors to heat and electric current; metals tend to be ductile, malleable, and shiny
|
|
|
noble gases
|
an element in group 8A of the periodic table; the s and p sublevels of the highest occupied energy level are filled
|
|
|
non-metals
|
an element that tends to be a poor conductor of heat and electric current; non-metals generally have properties opposite to those of metals
|
|
|
periodic law
|
when the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties
|
|
|
representative element
|
an element in an "A" group oin the periodic table; as a group these elements display a wide range of physical and chemical properties. In their atoms, the s and p sublevels in the highest occupied energy level are partially filled.
|
|
|
transition metal
|
one of the Group B elements in which the highest occupied s sublevel and a nearby d sublevel generally contain electrons.
