Question

Name three compounds that are present in earth are totaly black in colour​

Answer 1

Answer:

Each element has a name. Many of these names are already familiar to you - gold, silver, copper, chlorine, platinum, carbon, oxygen, and nitrogen. The names themselves are interesting. Many refer to a property of the element. The Latin name for gold is aurum, meaning "shining dawn." The Latin name for mercury, hydrargyrum, means "liquid silver."

The practice of naming an element after one of its properties continues. Cesium was discovered in 1860 by the German chemist Bunsen (the inventor of the Bunsen burner). Because this element imparts a blue color to a flame, Bunsen named it cesium from the Latin word caesius, meaning "sky blue."
