| Who developed the first periodic table in 1869? | Dmitri Mendeleev(a Russian scientist) |
| How is the periodic table arranged? | elements are arranged by atomic number and properties |
| How are the elements divided in the periodic table? | into metals, nonmetals, & metalloids |
| What are common properties of metals? | luster, ability to conduct heat & electricity, malleability, & ductility |
| How do metals vary from one another? | hardness, melting point, & reactivity |
| What happens when metals are grouped together? | thier electrons are free to move |
| What are the groups of metals? | alkali metals, alkaline earth metals, transition metals, & rare-earth metals |
| What are properties of nonmetals? | do not have luster & are poor conductors of heat and electricity, solid nonmetals are usually dull & brittle, they are not malleable nor ductile, many nonmetals are gases at room temperature |
| What groups are the nonmetals and metalloids found? | boron group, carbon group, nitrogen group, oxygen group, halogens, and noble gases |
| The elements that combine with metals to form salts are called____________. | halogen |
| A patterm that repeats is called__________. | periodic |
| The shininess of a metal's surface is a property called____________. | luster |
| A mineral that contains relatively large amounts of one or more metal compounds is called a(n)________________. | ore |
| Elements that have properties of both metals and nonmetals are_____________. | metalloid |
| Some metals have ______________, a property that allows them to be shaped without breaking. | malleability |
