VOCABULARY 1.7
THE PERIODIC TABLE
ADVANCED- YOU NEED 10 INDEX CARDS
THE PERIODIC TABLE OF ELEMENTS
• The periodic table is an arrangement of the chemical elements.
• Ordered by their atomic number (number of protons), electron configurations, and
recurring chemical properties.

Start at 1:42 and play until end of periodic table.
PERIOD
• A period is the name given to a horizontal row of the periodic table.
• The periodic table has seven periods.
• Period 1 contains only two elements: hydrogen and helium.
GROUP OR FAMILY
• In chemistry, a group (also known as a family) is a column of elements in the periodic
table of the chemical elements.

METALS
• Majority of the elements are metals.
• A substance (as gold, tin, copper, or bronze) that has a more or less shiny appearance, is a
good conductor of electricity and heat.
NON-METAL
• A chemical element (as boron, carbon, or nitrogen) that lacks the characteristics of a
metal.
• The elements that are generally considered other nonmetals include hydrogen, carbon,
nitrogen, phosphorus, oxygen, sulfur, and selenium.
METALLOID
• An element (as boron, silicon, or arsenic) intermediate in properties between the typical
metals and nonmetals.
• They usually have some properties of metal.
ALKALI METALS
• The alkali metals are a group of elements in the periodic table.
• They are all in the first column of the periodic table.
• The only element in the first column that is not usually considered an alkali metal is
hydrogen.
• They are shiny, soft, metals. They are very reactive.

ALKALINE METALS
• The family of chemical elements called the alkaline earth metals consists of beryllium,
magnesium, calcium, strontium, barium, and radium. T
• These chemical elements occupy the second column of the periodic table.
TRANSITION METALS
• One of the elements in group 3-12 of the periodic table.
• This is most of the familiar metals like iron, copper, nickle, silver, and gold.
• Most are hard and shiny.
• They are good conductors of electricity.
INERT/NOBLE GAS
• Along the extreme right-hand column of the periodic table of elements is a
group know as the noble gases: helium, neon,
argon, krypton, xenon, and radon.
• Also known as the rare gases, they once
Were called inert gases, because scientists believed
them incapable of reacting with other
elements.
