3. Extremely reactive NEVER found in their pure state. 1 They are found in ionic compounds 2 3 Click the arrow to return to the table. They react vigorously with water Form ionic compounds (salts) in reactions with halogens 4 5

4. Alkaline Earth Metals Melts at extremely high temperatures Physically soft, not as soft as the alkali metals 1 2 Have an oxidation number of +2 3 Click the arrow to return to the table. 4 melt at such high temperature that they remain solids Shiny, and most have a white or silvery color. 5

5. Basic Metals They are malleable and can be beaten into a sheet. Most are good conductors of heat and electricity. 1 Most are Ductile and can be formed into a wire. 2 They have high melting points. 3 Click the arrow to return to the table. They are heavy and dense. 4 5

6. Halogens 7 electrons on the outer shell. They are malleable and can be beaten into a sheet. 1 2 When bonding with metals, they form ionic bonds, which are the strongest 3 Click the arrow to return to the table. halogens are diatomic, meaning that they exist as molecules with two atoms 4 All halogens are non-metals. 5

7. Noble Gases All gases at room temperature. Have a complete valence shell. 1 2 Low boiling points. 3 Click the arrow to return to the table. 4 High ionization energies. Noble gases are relatively nonreactive. 5

8. Non-Metals Solid nonmetals are brittle. Poor conductors of heat and electricity. 1 2 have the ability to gain electrons easily 3 Click the arrow to return to the table. Little or no metallic luster. 4 Display a wide range of chemical properties and relativities. 5

9. Rare Earth Tarnish readily in air Metals have high luster. 1 2 blows of rare earths, lanthanide and actinide. 2 3 Click the arrow to return to the table. Silvery, silvery-white, or gray looking metals. 4 Have high electrical conductivity 5

10. Semi metals Electro negativities between those of metals and nonmetals Make good semiconductors 1 The reactivity of the metalloids depends on the element with which they are reacting 2 3 Click the arrow to return to the table. 4 The boiling points, melting points, and densities of the metalloids vary widely Have intermediate conductivity 5

11. Transition metals Very hard Very high melting/boiling points 1 Electrons are loosely bound 2 3 Click the arrow to return to the table. Positive oxidation states 4 High electrical conductivity 5
