What is the mass of 2.50 mol of Helium?
Helium molecule is mono atomic. 1 mole = 6.023 x 1023 atoms of helium So, 2.5 moles = 2.5 x 6.023 x 1023 atoms of helium or 15.058 x 1023 atoms of helium
Is helium diatomic?
No. First consider two helium atoms, each has two electrons spin-paired in a filled 1s shell, for a total of 4 electrons. Now construct the molecular orbitals that a diatomic helium molecule would contain. To do so, you combine both 1s orbitals from the individual atoms. Combining two atomic orbitals gives two molecular orbitals (by orbital conservation). The in-phase overlap gives the bonding orbital (sigma 1s) and out-of-phase overlap gives the anti-bonding orbital (sigma* 1s). Filling in the two molecular orbitals from low energy to high energy (aufbau principle) populates the simga with two electrons and the sigma* with two electrons. Because the energy of the sigma and sigma* orbitals are equal, but opposite in sign, there is no net bond stabilization. I.e. no physical reason for Helium atoms to exist as diatomic molecules.
Is helium an ion?
Yes helium is an atom. It is stable. It is placed in group 18.Yes, helium is a monoatomic molecule. It is stable itself as it has already achieved maximum possible electrons in its outermost shell. It is the only element in group 18 without 8 electrons in valence shell.

What are the symbols for hydrogen and helium?
The chemical symbol for helium is "He."
Is helium an element molecule or mixture?
Helium is an element.
How many elements does helium have?
ONE, Helium is an element, not a molecule.
Is He a molecule?
Helium is monoatomic.
Is helium a compound molecule?
Helium is a chemical element, not a compound; also helium is monoatomic.
Is He diatomic molecule?
Helium is monoatomic.
Helium molecule has how many atoms?
Helium does not form molecules but exists as individual atoms.
Is helium a element or molicles?
Helium is an element. It is a chemical element with the symbol He and atomic number 2. Helium exists as individual helium atoms, not molecules.

How many atoms are in a molecule of helium?
Helium does not form molecules but exists solely is individual atoms.
Does helium bend?
If your asking if a molecule or compound containing helium is a "bent" molecule like water, then the answer is no. Helium is one of the noble or inert gases, which fulfill the octet rule and do not need to bond in order to share or transfer electrons. Hence the noble gases and helium will not react, even with another atom of the same element. So in short, since helium won't bond with any other atom to become a molecule or compound, there is no way for it to be bent. Of course, I interpreted "bend" with the structure of a molecule... this may not be what you're looking for, in which case you will have to be more specific.
