The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent
Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
