Where was boron discovered?
Compounds of boron have been around since ancient times, Egyptian mummification could not have been accomplished without it. Boron is not a naturally free element. The element was not isolated until 1808 and it was not identified as the element boron until 1824. See the related link for more information on this subject.
Who discovered the organomagnesium compounds?
The person that is credited with discovering the organomagnesium compounds was Victor Grignard. He found them and used them to make synthetic reagents and win the 1912 Nobel Peace Prize for it.
Who was boron doscovered by?
Boron was discovered by Joseph-Louis Gay-Lussac and Louis-Jaques Thénard, French chemists, and independently by Sir Humphry Davy, an English chemist, in 1808. They all isolated boron by combining boric acid (H3BO3) with potassium. It was incompletely refined and was not recognized as an element. It remained for the Swedish chemist Jöns Jakob Berzelius to actually identify boron as an element, which he did in 1824.
When was calcium discover?
It was discovered by Sir Humphrey Davy in 1808. Calcium was known and used in various compounds from as early as Roman times, but the element itself was not actually isolated until 1808.

Who credited boron?
Sir Humphrey Davy isolated boron in 1808. The first to realize it was an element was probably John Jakob Berzelius. Boron compounds had been known for thousands of years.

What is the history of the boron element?
Jöns Jakob Berzelius identified boron as an element in 1824. It was isolated by Sir Humphrey Davy, Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808. The first pure boron was produced by the American chemist W. Weintraub in 1909, although this is disputed by some researchers.

Who invented calcium?
Sir Humphry Davy and Jöns Jakob BerzeliusThe element Calcium was first discovered by Sir Humphry Davy, a British Chemist, in 1808, in England, through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).Calcium was known to the ancients, in the form of lime (calcium oxide, CaO). Sir Humphry Davy first isolated the element in 1808, by electrolyzing a mixture of lime and mercuric oxide (HgO).He was inspired by the experiments of Swedish chemist Jöns Jacob Berzelius, who had attempted the same thing, but failed to isolate the elemental calcium from the resulting compound.He named it calcium after the Latin word "calx" which is what the Romans called lime.
