Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons.
A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with two neutrons, depending on the isotope, held together by the strong force.
Helium has two protons and two neutrons in its nucleus, and two electrons in one shell. It is located in group eighteen, period one and block s of the periodic table. Colourless, odourless gaseous nonmetallic element.
18 de ene. de 2024 · The atom calculator is a tool for calculating the atomic number and the mass number based on the number of atom components - protons, neutrons, and electrons (or vice versa). In addition, you can define the charge of ions with known numbers of protons and electrons.
