Term
|
Definition
| Oxygen atoms are positioned in the corners of a tetrahedron, a pyramid like shape with four triangular faces. Si has a charge of plus 4 and oxygen a charge of minus 2. |
|
|
Term
|
Definition
| The tetrahedral are independent and do not share any oxygen atoms. |
|
|
Term
|
Definition
| In a single chain silicate, the tetrahedral link to form a chain by sharing two oxygen atoms. |
|
|
Term
|
Definition
| The tetrahedral form a double chain by sharing two or three oxygen atoms. |
|
|
Term
|
Definition
| The tetrahedral share three oxygen atoms and therefore link to form two-dimensional sheets. |
|
|
Term
|
Definition
| Each tetrahedron shares all four oxygen atoms with its neighbors, forming a three-dimensional structure. |
