ELEMENTS AND THE PERIODIC TABLE Chapter 5.5

PERIODIC TABLE  A structured arrangement of elements that helps us to explain and predict physical and chemical properties.  Complete Periodic table at back of text  The periodic table is put into two categories: Metals and Nonmetals

 Metals are arranged towards the left side of the table.  Examples: Sodium, Potassium, Lithium, and calcium  Nonmetals are generally found on the right side of the table  Examples: Carbon, oxygen, fluorine, and chlorine  One Exception: Hydrogen (H) – behaves mostly as a nonmetal even though it is located in the top left corner of the periodic table.

CHEMICAL FAMILIES  CHEMICAL FAMILIES  CHEMICAL FAMILIES – are groups of elements in the same vertical column of the periodic table.  They have similar physical and chemical properties.

Period period  A period is a horizontal row of elements whose properties gradually change from metallic to nonmetallic from left to right along the row.

Group of One  Hydrogen is a unique element.  It’s most common isotope has only a single proton and no neutron in its nucleus.  Hydrogen doesn’t have much in common with the alkali metals. It’s a colorless, odorless, tasteless, highly flammable gas.  Almost all of Earth’s hydrogen exists in combination with other elements. Its reactivity is too great for it to exist in the atmosphere as a free element.

ALKALI METALS  Are the family of elements in Group 1.  They are soft, silver-colored metals that react violently with water to form basic solutions.  Therefore very soluble in water  EXAMPLES: lithium, sodium, potassium

ALKALINE EARTH METALS  Are the family of elements in Group 2.  They are light, reactive metals that form oxide coatings when exposed to air.  Often insoluble in water  Also shiny, silver metals  EXAMPLES: magnesium (Mg), calcium, and barium (Ba)

Metalloids  The staircase  Elements that possess both metallic and nonmetallic properties. Found on both sides of the zigzag line that divides the metals from the non-metals.  Ex. boron (B), silicon (Si), germanium (Ge) arsenic,, antimony, tellurium, polonium.

HALOGENS  Are the elements in Group 17.  They are extremely reactive, with fluorine being the most reactive.  Nonmetallic elements are all poisonous elements that react readily with sodium and other alkali metals  Second column from the right on the periodic table  EXAMPLES: fluorine (F), chlorine (Cl), bromine (Br)

NOBLE GASES  Are the elements in Group 18.  They are located in the far right column.  They are special because of their extremely low chemical reactivity.  The noble gases are of special empirical and theoretical interest to chemists.  Generally noble gases do not form compounds.  EXAMPLES: Helium (He), neon (Ne)

REPRESENTATIVE ELEMENTS  Are the elements in Groups 1,2 and  Of all the elements, the representative elements best follow the periodic law.  The laws and theories presented in introductory chemistry courses are often restricted to these elements.

TRANSITION ELEMENTS  Are elements in Groups 3 to 12.  These elements exhibit a wide range of chemical and physical properties.

HOMEWORK  Periodic Table Review sheet.  Use page and the Periodic table at the back of the book to complete the handout.
