2 The Father of the Periodic Table Dimitri Mendeleev _______________was the first scientist to notice the relationship between the __________ _______________was the first scientist to notice the relationship between the __________ Arranged his periodic table by ________ _______ Arranged his periodic table by ________ _______ Said properties of ___________elements could be predicted by the properties of elements around the missing element Said properties of ___________elements could be predicted by the properties of elements around the missing element _________later discovered that the periodic nature of the elements was associated with_________ _________, not atomic mass _________later discovered that the periodic nature of the elements was associated with_________ _________, not atomic mass Mendeleev elements atomic mass unknown Moseley atomic number

3 What does the information in the box tell me? 1H1.008 Atomic Number = # of __________ Atomic Mass = # of _________ + # of __________ __________ Symbol protons Elemental protons neutrons

4 The Periodic Table Column = Group or___________ _____ columns on the Periodic Table Row = __________ _____ rows on the Periodic Table Family Period 18 7

5 Metals, Nonmetals, and Semi- metals Metals are on the _________ side of the stair- step ____________ is the only nonmetal on the ___________ side ______________ are on the right of the stair-step Semi-metals or _____________ touch the stair-step Hydrogen Nonmetals left metalloids metal

6 Periods = Rows In the periodic table, elements have something in common if they are in the same row. All of the elements in a period have the same number of atomic orbitals.atomic orbitals Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that.electrons

7 Groups = Columns (called Families) The elements in a group have the same number of electrons in their outer orbital. Every element in the first column (group one) has one electron in its outer shell. Every element on the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell. There are some exceptions to the order when you look at the transition elements, but you get the general idea. transition elements

8 ALKALI METALS Group 1 Hydrogen is _____a member, it is a non-metal _____ electron in the outer shell Soft and silvery _________ Very _____________, especially with water Conduct _____________ NOT 1 metals reactive electricity

9 ALKALINE EARTH METALS Group 2 ____ electrons in the outer shell White and malleable (able to be ___________ Reactive, but less than Alkali metals Conduct electricity 2 molded

10 TRANSITION METALS Groups in the middle Good conductors of heat and electricity Some are used for _____________ The transition metals are able to put up to _____ electrons in their second to last shell Can ________ with many _________in a variety of shapes jewelry 32 bond elements

11 BORON FAMILY Group 3 ____ electrons in the outer shell ______ are metals Boron is a _____________ 3 Most metalloid

12 CARBON FAMILY Group 4 ___ electrons in the outer shell Contains metals, metalloids, and a _____________ Carbon (C) 4 Non-metal

13 NITROGEN FAMILY Group 5 ____ electrons in the outer shell Can _________ electrons to form compounds Contains metals, metalloids, and non-metals 5 share

14 OXYGEN FAMILY Group 6 ____ electrons in the outer shell Contains metals, metalloids, and non-metals _____________ 6 Reactive

15 Halogens Group 7 ____ electrons in the outer shell _____ are non- metals ________ ____________- are often bonded with elements from Group 1 7 ALL VERY REACTIVE

16 Noble Gases Group 8 Exist as gases Non-metals ____ electrons in the outer shell = _________ Helium (He) has only ____ electrons in the outer shell = Full ____ ___________ with other elements 8 FULL 2 NOT REACTIVE

17 Rare Earth Metals (Special rows on the Periodic Table) Some are _____________ The rare earths are silver, silvery- white, or gray metals. Conduct electricity Actinides Lanthanides radioactive
