Helium is a very light, non-reactive gas<\/strong>. It\u2019s the second most abundant element in the universe<\/strong> (after hydrogen) and was first discovered not on Earth, but in the Sun!<\/strong> \u2600\ufe0f<\/p>\n\n\n\n Helium has a full outer electron shell<\/strong>, which makes it extremely stable and unreactive<\/strong> \u2014 a typical trait of noble gases<\/strong>.<\/p>\n\n\n\n Helium is the second lightest element<\/strong> and does not support combustion<\/strong>, which means it won\u2019t catch fire. Unlike hydrogen (which is flammable), helium is safe for balloons and blimps<\/strong>. \ud83c\udf88<\/p>\n\n\n\n It\u2019s found in natural gas reserves<\/strong> and extracted through a process called fractional distillation<\/strong>.<\/p>\n\n\n\n Helium is more than just a party balloon gas \u2014 it\u2019s a safe, stable, and essential element<\/strong> for science, medicine, and technology. From cooling machines to lifting balloons<\/strong>, helium proves that even the lightest elements<\/strong> can have a big impact. For students, helium is a fun way to learn about gases, space, and chemistry in real life<\/strong>. \ud83d\udd2c\ud83c\udf20<\/p>\n\n\n\n \ud83d\udd39 Basic Information Helium is a very light, non-reactive gas.
