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

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

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

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

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

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

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

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

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