No. helium is a gas and gases do not from crystals.
Crystal structure is for solids and for gases. Helium is a gas and doesn't form any crystal.
Helium does not have a crystal structure at normal conditions because it remains as a gas due to its low boiling point. However, under extremely low temperatures close to absolute zero, helium can form a hexagonal close-packed crystal structure.
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
Helium has a nucleus with 2 protons, 2 neutrons. It has only one energy level with 2 electrons in it.
The He2 molecular orbital (MO) diagram is important for understanding how the two helium atoms in a helium dimer bond together. It shows the energy levels and arrangement of electrons in the molecule, which helps explain the bonding and electronic structure of the helium dimer.
The helium energy level diagram helps us understand how electrons are arranged in the helium atom. It shows the different energy levels that electrons can occupy, and how they are filled according to the rules of quantum mechanics. This diagram is important because it helps us predict the behavior of helium and other elements based on their electronic structure.
Helium is a monatomic gas. That is its atoms do NOT combine with anything. It is the most unreactive of all elements.
An alpha particle.
An alpha particle.
Neptune is made of hydrogen,helium,molecular and a some ice.
