Is helium a monatomic or diatomic molecule
WebConcept: The molecules of elements can be monoatomic, diatomic, triatomic, and so on, depending on the number of atoms in each molecule of the element. This is called atomicity. ∙ Monoatomic: The elements that have only one atom in a molecule are called monoatomic. They are stable. Example: Ne,Ar (noble gases). WebApr 4, 2024 · Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.
