IF YOU HOLD GALLIUM IT WILL BEGIN MELTING IN YOUR HAND

IF YOU HOLD GALLIUM IT WILL BEGIN MELTING IN YOUR HAND
Before the discovery of gallium its existence and main properties were predicted by Russian chemist Dmitri Mendeleev.
He named the hypothetical element eka-aluminum as he predicted the element would sit below aluminum on the periodic table.

Gallium was discovered by French chemist Paul E. Lecoq de Boisbaudran through a spectroscope in 1875 in Paris.

Its now characteristic spectrum (two violet lines) identified it as a new element.

De Boisbaudran extracted gallium in the first instance from a zinc blende ore from the Pyrenees and obtained initially only 0.65 grams from 430 kilograms of ore. He isolated gallium by electrolysis of its hydroxide in potassium hydroxide solution.

The origin of the name comes from the Latin word ‘Gallia’, meaning France.

Gallium is considered to be non-toxic.

Gallium has a melting temperature of about 85 degrees Fahrenheit, which is basically room temperature. If you hold this metal it will begin melting in your hand.
