Contributions to Electronics • Sir Davy was the first to discover that different materials attract electrons better than others. • These were called batteries
Davy eventually discovered magnesium, calcium, strontium, and barium in 1808 Barium is used to make spark plugs, and is used for coating fluorescent light bulbs Contributions to ElectronicsAgain!!!!!!!!!
Contributions to ElectronicsSome More!!!!!!!!!!!!!!!!!!! • Magnesium is used for combining metals and refine titanium • Calcium is used for constructing cement and mortar. It is also used for detecting carbon dioxide
Contributions to Electronicsfor the Last Time • Strontium is used in studies of neurotransmitter release in neurons and in glass for colour television cathode ray tubes to prevent X-ray emission
