Helium has only 2 electrons in its outer electron shell, so 2 dots.
they are formed by atoms of different types mixing together
At the top of a chemical diagram, you would typically find chemicals that are less reactive or inert, such as noble gases like helium, neon, and argon. These elements have full outer electron shells and tend not to form compounds with other elements.
Helium has the least number of neutrons among the elements listed.
Helium has one energy shell with only 2 electrons in it.
Helium and magnesium are both elements because they consist of only one type of atom. In contrast, compounds are made up of two or more different elements chemically bonded together. Helium and magnesium exist in their pure forms as single atoms without being chemically combined with other elements.
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 does not form chemical bonds with other elements, including hydrogen. Hydrogen, however, can bond with other elements like oxygen, carbon, and nitrogen to form various compounds.
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.

Helium is one element and does not chemically react.

Technically, any elements less massive than iron can fuse together; however, practically it is easier to fuse the lightest elements (Hydrogen, Helium...), which also give higher energy yields. Any elements which are heavier than iron (or are iron) will not fuse, and instead decay via nuclear fission.

No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
