youtrb+Helium!

Hi my name is Youtrb, and I would like to talk to you about the amazing Helium ! Helium's atomic number is 2. Helium has 2 electrons (the 2 dots on the picture!). Helium is a noble gas. Helium is used for many things, like filling up balloons and blimps for parties and merchandise like the blimp for Hood! Helium is a non-toxic gas, so it does not harm humans or animals! Helium is the second lightest gas in the table of elements! It's used for low-temp cooling systems too!

The first evidence of helium was observed on August 18, 1868 as a bright yellow line of 587. nanometers in a spectrum of the chromosphere of the sun by a French astronomer Pierre Jansen, during a solar eclipse in India. Helium goes way far back! The first sight of helium was on the sun, but an Italian physicist named Luigi Palmieri detected helium on earth for the first time on March 26, 1882 and on March 26, 1895 a British chemist, Sir William Ramsay, isolated helium on earth by treating the mineral cleveite with mineral acids!

A long time ago people from a company that made blimps filled up a blimp
