Study Notes
Properties of Nonmetals
- Nonmetals are typically poor conductors of electricity and heat when solid
- Nonmetals are brittle and lack the ability to be molded into different shapes
Characteristics of Nonmetals
- A characteristic of nonmetals is that they tend to gain electrons to form anions
Distribution of Elements
- Nonmetallic elements make up the overwhelming majority of the Earth's crust, atmosphere, oceans, and biosphere
Industries Involving Nonmetals
- Nonmetallic elements are integral to industries such as manufacturing, construction, and agriculture
Nature of Oxides of Nonmetals
- Oxides of nonmetals tend to be acidic
Organic Compounds
- Carbon and hydrogen, along with other elements, are present in organic compounds according to many authors
- The defining characteristic of organic compounds is that they contain carbon-hydrogen bonds according to some authors
- Glucose, a carbon-containing compound, is considered organic
Classification of Organic Compounds
- The primary reason for the classification of millions of compounds as organic is the presence of carbon-hydrogen bonds
- Mineral carbonates and cyanides are generally considered inorganic, despite containing carbon
