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.

Helium - Element information, properties and uses

WebHelium has atomic symbol He, and atomic number 2. The element helium is a noble gas in group 18, the last group of elements on the periodic table. It is the second lightest element, and the most inert. It lies above neon, element 10. Helium has 2 electrons, which completes its valence shell, the 1s shell. WebHelium is composed of two electrons, two protons, and usually two neutrons. It is a colorless, odorless, inert gas. Helium is a byproduct of both fusion and fission. In 1868, Helium was first detected in the sun's spectrogram. Its name is derived from the Greek word, 'helios' meaning sun. Helium atom proton electric charge diagram. harrison cheung
