History
Name | Phosphorus | Calcium |
History | The element Phosphorus was discovered by H. Brand in year 1669 in Germany. Phosphorus derived its name from the Greek word phoosphoros, 'carrying light'. | The element Calcium was discovered by H. Davy in year 1808 in United Kingdom. Calcium derived its name from the Latin calx, meaning 'lime'. |
