which lithium isotope is more abundant

In 1790's, the Brazilian joz é bonif á ciode andralda e Silva discovered the first lithium mineral petal stone lialsi4o10 in uto Island, Sweden It was observed that when it was thrown on the fire, it would emit a strong crimson flame In 1817, Johan August arfvedson of Stockholm analyzed it and concluded that it contained a previously unknown metal, which he called lithium. He realized that it was a new alkali metal and a lighter sodium But unlike sodium, it cannot be separated by electrolysis In 1821, William Brande got very little money in this way, but it was not enough for measurement It was not until 1855 that Robert Bunsen, a German chemist, and Augustus Matthiessen, a British chemist, were able to obtain them in bulk by electrolysis of molten Lithium Chloride. why lithium batteries are bad
