Alkali Metals
Group 1, 1 electron in outer level, very reactive, soft, silver, shiny, low density; Lithium, Sodium, Potassium, Rubidium, Cesium, Francium
Alkaline Earth Metals
Any metal in group 2A of the periodic table
a negatively charged ion
Atomic Radius
one-half of the distance between the center of identical atoms that are not bonded together.
a positively charged ion
the tendency of an atom or radical to attract electrons in the formation of an ionic bond
group 17; contains nonmetals; 7 electrons in its outermost energy level; very reactive; poor conductors of electric current; never in its uncombined form in nature; combine with most metals to form salts
Inner Transition Metal
a type of group B element that is contained in the P-block of the periodic table and is characterized by a filled outermost S orbital, and filled or partially filled 4F and 5F orbital
a particle that is electrically charged (positive or negative)
Ionization Energy
the amount of energy required to remove an electron from an atom
elements that have characteristics of metals and nonmetals
have a shiny or metallic luster, good conductors of heat and electricity
Noble Gases
one of the elements of group 18 of the periodic table(helium, neon,argon, krypton, xenon, and radon); noble gases are unreactive
elements that are usually dull in appearance, poor conductors of heat and electricity, gases at room temperature
Periodic Law
the principle that chemical properties of the elements are periodic functions of their atomic numbers
Representative Elements
a group in the periodic table which includes metals, metalloids, and nonmetals
Transition Metal
An Element in group 3 through 12 of the periodic table
