1 The Periodic Table Name: Mendeleev Russian chemist in Arranged elements in rows with similar and increasing Left blanks for elements Modern Periodic Table Elements arranged by Periods- across the table Groups- (also called family) Periodic Law-pattern of properties Classes of Elements Metals of elements of the table Nonmetals Only elements of the table Metalloids Share properties of and between metals and nonmetals Left to, elements become metallic and more nonmetallic Do pages skip box on page 49 Alkali Metals Group 1 A Found only as in nature Reactivity increases as you go the column Have only valence electron Li, Na, K, Rb, Cs, Fr Lithium, Sodium,, Rubidium, Cesium, 1

2 Alkaline Earth Group 2 A than Alkali Metals Reactivity as you go down the column Have only valence electron Be, Mg, Ca, Sr, Ba, Ra Beryllium,, Calcium, Strontium,, Radium Transition Metals Found in the Make compounds Boron Group Group 3 electrons B, Al, Ga, In, Tl Carbon Group Group 4A valence electrons C, Si, Ge, Sn, Pb Halogens Group 7 valence electrons React with metals Reactivity increases as you go up the group F, Cl, Br, I, At Lanthanides and Actinides Found at the Many and man-made Called metals Nitrogen Group Group 5 valence electrons N, P, As, Sb, Bi Oxygen Group Group 6A valence electrons O, S, Se, Te, Po Noble Gases Group 8 valence electrons Extremely Colorless,, found in neon lights He, Ne, Ar, Kr, Xe, Rn Do pages skip box on page 51 2

4 Periodic Table Basics 1. The vertical columns on the periodic table are called. 2. The horizontal rows on the periodic table are called. 3. Most of the elements in the periodic table are classified as. 4. The elements that touch the zigzag line are classified as. 5. The elements in the far upper right corner are classified as. 6. Elements in the first group have one outer shell electron and are extremely reactive. They are called. 7. Elements in the second group have 2 outer shell electrons and are also very reactive. They are called. 8. Elements in groups 3 through 12 have many useful properties and are called. 9. Elements in group 17 are known as salt formers. They are called. 10. Elements in group 18 are very unreactive. They are said to be inert. We call these the. 11. The elements at the bottom of the table were pulled out to keep the table from becoming too long. The first period at the bottom called the. 12. The second period at the bottom of the table is called the. 4

5 Color Coding the Periodic Table This worksheet will help you understand how the periodic table is arranged. Your teacher will give you a copy of the periodic table to color. Using colored pencils, color each group on the table as follows: 1. Color the square for Hydrogen pink. 2. Color all the lanthanides red. 3. Color all the actinides green. 4. Color all the other metals yellow. 5. Place black dots in the squares of all alkali metals. 6. Draw a horizontal line across each box in the group of alkaline earth metals. 7. Draw a diagonal line across each box of all transition metals. 8. Color the metalloids purple. 9. Color the nonmetals orange. 10. Draw small brown circles in each box of the halogens. 11. Draw checkerboard lines through all the boxes of the noble gases. You do not need to turn this page in 5
