✰ PERIODIC TABLE - FAMILIES, GROUPS, and PERIODS

Terms in this set (19)

family
A group of elements on the periodic table with similar physical and chemical properties
group
a vertical column of elements in the periodic table
Period
A horizontal row of elements in the periodic table
alkali metals
Family of elements that reacts the quickest with other elements, can only naturally occur in compounds, have the lowest densities of all metals, and are soft and silvery. (Group 1)
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium
Elements in the alkali metal family?
alkaline earth metals
react quickly to other elements, but slower than alkali metals. they do not occur naturally, have a soft and silver appearance, and have a low density that is still greater than alkali. (Group 2)
Beryllium, Magnesium, Calcium, Strontium, Barium, Radium
Elements in the Alkaline earth metal family are?
transition elements/metals
have the highest density and can be found in a pure state. have high melting points. can be used in building materials, jewelry, electrical wires, coins, paints and pigments
Iron, Cobalt, Nickel, Copper, Zinc, etc.
Transition metal examples?
Halogens
Elements ready quickly with metals and can form salts with the alkali metals. Only occur naturally in compounds. Can react with other non metals (group 17)
fluorine, bromine, chlorine, iodine
Examples of Halogens.
Noble gases
Do not react with other elements (group 18)
Helium, Neon, Argon, Krypton, Xenon, Radon
Examples of the noble gases are?
7
