One standard test for early chemists was a taste test. Beryllium was found to have a sweet taste.Beryls are minerals with chemical formula Be 3Al 2(SiO 3) 6 that come in many different colors. Beryllium was discovered while investigating beryls.Beryllium has the highest melting point of the light metals.These tools are vital in environments where the risk of flames or explosions are high. Beryllium tools are made to prevent sparking when the tool strikes another metal.Beryllium is added to alloys to increase electrical and thermal conductivity.Beryllium is a soft, silvery-white metal with low density.It decays into 10B by β- decay with a half-life 1.36 million years. It contains 5 neutrons and is stable.īeryllium-10 is a radioactive isotope containing 6 neutrons. Its half-life is 53.12 days.īeryllium-9 is the most common natural isotope. It decays into 7Li through electron capture. Two other isotopes can be found in trace amounts.īeryllium-7 is a radioactive isotope containing 3 neutrons. ![]() He named the element beryllium after the Greek word beryllos for beryl.īeryllium is nearly 100% beryllium-9. ![]() He first named the substance Earth of beryl, but switched to glucenum to reflect the sweet taste. Wöhler proposed changing the name from the taste property since there are many elements with a sweet taste. Name Origin: Vauquelin named his element after the substance he was investigating, beryl. Pure beryllium was first isolated in 1828 by German chemist Friederich Wöhler and French chemist Antoine Bussy independently from each other. He isolated a compound containing an unknown element with a sweet taste. ![]() Beryls come in a wide variety of colors, but seem to have similar chemical attributes. Vauquelin was investigating the chemical properties of beryls. Electron Configuration: 2s 2 (shorthand) or 1s 22s 2 (full)ĭiscovery: Louis-Nicholas Vauquelin in 1798.
