Silicon Symbol: 2814 Si Uses: computer chips, but not silicone – a plastic like substance
Phosphorus Symbol: 3115 P Uses: occurs in 3 forms – white (dangerous!), red and black; found in pyrotechnics
Sulfur Symbol: 3216 S Uses: also known as brimstone; smells just awful
Chlorine Symbol: 3517Cl Uses: used as one of the first forms of chemical warfare; often used as bleach to disinfect
Argon Symbol: Ar Uses: Also in fluorescent lights – blue in colour!
Potassium Symbol: 3919 K Uses: part of fertilizer, very reactive with water; found in bananas
Calcium Symbol: Ca Uses: rare in pure form, but as a compound is key to bones and teeth
