Properties of Helium Element – Symbol He - Nuclear Power
WebHelium is named after the Greek word for the sun, helios, as it was first identified in the sun’s corona (the sun is composed of 25% helium). The second most abundant element in the universe, helium is scarce on Earth. A product of nuclear fusion and radioactive decay, it is the lightest noble gas, colorless, odorless, and inert with a low ... WebThe mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.

WebHelium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebHelium is primarily used in altitude research and meteorological balloons. In autogenous welding, it is used as an inert protective gas. It is the only cooler capable of dropping temperatures below 15K (-434oF). Helium is also used in the manufacture of germanium and silicon crystals.
