| Chemically, elements can be classified as metals, metalloids, or non-metals based, in part, upon these physical properties. |
|
| This award-winning site has a number of sections relating to alkaline earth metals, transition metals, other metals and metalloids. |
|
| The properties of the semimetals, or metalloids, lie between those of the metals and the nonmetals. |
|
| The metalloids have an intermediate number of valence electrons. |
|
| Inasmuch as chemical properties determine toxicological properties, metalloids should not be considered as a subset of metals but as a subset of nonmetals. |
|
| It reacts with many metals and metalloids to form phosphides. Phosphorus atoms can bond with oxygen atoms to form ester groups. |
|
| Binary compounds of zinc are known for most of the metalloids and all the nonmetals except the noble gases. |
|
| Heavy metals and metalloids mercury, arsenic, lead, cadmium, selenium, nickel, copper, etc. |
|
| The forensic toxicologist told the court the metals or metalloids may have been ingested on one or more occasions. |
|
| The metalloids are adjacent to a diagonal line from boron to polonium. |
|
| The projects are delivering geoscience knowledge, in partnership with other groups on specific issues that deal with potentially toxic metals and metalloids in the environment. |
|
| Such complex composite materials do not only contain aluminium, but also metalloids and precious metals such as copper, silver, gold and platinum. |
|
| Emphasis is placed on a small group of naturally occurring elements, chiefly metals and metalloids, derived from geological sources that can represent health risks. |
|
| Hydrogen also forms compounds with less electronegative elements, such as metals and metalloids, where it takes on a partial negative charge. |
|
| The paper, written by researchers at Yale University, identified 62 metals or metalloids used to make a range of products. |
|
| Recognising the signs of teething, Sophie replaced the nourishing metalloids with plastic teething rings. |
|
| Recent findings on the phytoremediation of soils contaminated with environmentally toxic heavy metals and metalloids such as zinc, cadmium, lead, and arsenic. |
|
| Yesterday, at Birmingham Crown Court toxicologist Professor Robin Braithwaite said elevated levels of metals or metalloids were found in her blood when it was tested. |
|
| Researchers at Yale University, led by Prof Thomas Graedel, analysed the use of 62 metals or metalloids commonly found in popular technology, such as smartphones. |
|
| The raw material suppliers for the mold release agents identified in the study are the various natural oils, waxes, petroleum, and metalloids suppliers. |
