| They consist of metals and nonmetals bound together in a crystalline or non-crystalline structure. |
|
| Potassium also reacts readily with all acids and with many nonmetals, such as sulfur, fluorine, chlorine, phosphorus, and nitrogen. |
|
| In contrast most other nonmetals tend to form polyatomic molecules in the gaseous state. |
|
| Known as the native elements, they are partitioned into three families: metals, semimetals, and nonmetals. |
|
| The nonmetals have a tendency to react chemically with metals and gain electrons to form negative ions. |
|
| Expenditures were up for all other commodity groups, but especially for the nonmetals. |
|
| The relatively few nonmetals appear in the upper right-hand section of the chart except for hydrogen. |
|
| Exploration expenditures for nonmetals were third in 1993 after those for precious metals and base metals. |
|
| Alkaline Earth Metals: Very reactive elements that form ionic compounds with nonmetals. |
|
| No. 26-201-XIB 1 Confidential information excluded from nonmetals p Preliminary Note: Numbers may not add to totals due to rounding. |
|
| Inasmuch as chemical properties determine toxicological properties, metalloids should not be considered as a subset of metals but as a subset of nonmetals. |
|
| The native nonmetals diamond, fullerene, graphite, and sulfur are structurally distinct from the metals and semimetals. |
|
| An analogous technique, applicable to nonmetals, employs an electrically charged liquid smeared on the material surface. |
|
| Binary compounds of zinc are known for most of the metalloids and all the nonmetals except the noble gases. |
|
| The largest contributor to the value of nonmetals production was potash. |
|
| Metalloids have electronic structures intermediate between the nearly empty outer electron shells of the typical metals and the nearly filled electron shells of the nonmetals. |
|
| Nonmetals with eight valence electrons are chemically unreactive. |
