Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table.

We’ll use a Bohr diagram to visually represent where the electrons are around the nucleus of the He atom. Electrons are placed in energy levels in a predictable pattern. The first energy level...

Helium (He). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of helium-4 (atomic number: 2), the most common isotope of the element helium. The nucleus consists of 2 protons (red) and 2 neutrons (orange).

Here we see a schematic diagram of a helium atom in its lowest energy state. Two protons are present in the nucleus of all helium atoms. In the most common variety of helium, the nucleus also contains two neutrons, which have nearly the same mass as the proton but carry no charge.

Learn about the orbital diagram of helium and understand how its electron configuration works. Explore the arrangement of electrons in helium's orbitals and discover the stability of its configuration.

Explore the helium orbital diagram, including its orbital notation, energy levels diagram, and molecular orbital structure, with step-by-step guidance.

Learn about the helium atom's structure with the help of the Bohr model diagram. Understand the arrangement of electrons and energy levels within the helium atom.

Mar 11, 2025 · To draw the Bohr model of helium, note the 2 protons, 2 neutrons, and 2 electrons. Start by illustrating the nucleus, and then depict the first electron shell. Contents

This diagram visually represents the arrangement of electrons in a helium atom and helps to understand its basic atomic structure. It shows that helium has a stable electron configuration since the first shell is completely filled with 2 electrons.

The Lewis dot diagram of helium consists of two dots, each representing one of its two valence electrons. These electrons occupy the first energy level, or the closest orbit to the nucleus, giving helium a stable and inert electronic configuration.
