What's in a Periodically Inspired Taco?
★ Ta: Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers.
★ C: Carbon- A diamond is forever, unless you heat it too much and it burns up into Carbon Dioxide gas. Graphite is also pure carbon and widely used in pencils, but not nearly as pretty.
★ O: Oxygen makes up 21% of the atmosphere, and is what you breathe in to survive!
★ S: Sulfur is one of the few elements found pure in nature. Also called brimstone, it oxidizes and is responsible for the characteristic smell of many volcanoes.
