Te hinu hau

He hauhautanga te hau helium, he maha nga mahi rereke ka taea. Me ako iti ake mo tenei hau motuhake me nga waahanga e rima e whakamarama ana he aha te helium, no hea, me te mea nui. No hea te helium? Ko te hau helium he momo hau e kore e kitea, e hongi ranei. He tino maamaa, he maha nga ahuatanga motuhake.

History

Way back in 1868, a French scientist named Jules Janssen found helium in the sun. After this great discovery, people began to find helium in rocks and pure gas on Earth. But where does all that helium come from? Well, helium is formed. It drifts into a gas when certain things in rocks break down. This mainly happens when rocks composed of uranium and thorium decay over millions of years. Whenever these substances split, they emit tiny particles called alpha particles.  AGEM haumāmā is quite small, and they combine with electrons, which are even tinier, to form helium atoms. 

He aha i whiriwhiri ai i te hau Helium AGEM?
