Study Notes
Non-metals are elements that do not conduct electricity well. They have different properties compared to metals, making them unsuitable for many applications. Here is some information about their characteristics and examples:
Properties: Unlike metals, which can conduct both heat and electricity, non-metals generally cannot conduct heat very effectively, although they may still conduct electricity somewhat. This makes them useful for insulation materials like wood, foam, rubber, glass, and plastics. In addition, non-metal atoms tend to gain electrons more easily than metal atoms, allowing them to form ionic bonds with each other. While non-conducting compounds made from non-metals interact poorly with water due to weak hydrogen bonding, certain non-metal alloys can react with strong acids because they contain a small amount of heavy metal such as lead.
Examples: Some common non-metals include carbon, nitrogen, oxygen, and sulfur. Carbon is found in graphite, diamond, coal, and charcoal; it's also used to make steel and concrete stronger. Nitrogen forms air and is essential for life on Earth. Oxygen forms the atmosphere and combines with other chemicals to create rust. Sulfur is necessary for all animals and plants. There are three types of non-metallic matter — covalent solids, ionic solids, and metalloids — each having its own set of unique chemical and physical properties.
In summary, non-metals exhibit distinct properties, including poor electric conductivity and limited reactions with water. Their uses range from simple household items like rubber to complex industrial processes involving artificially grown crystals. Knowledge of these properties helps scientists mix together ingredients into new products effectively.
