It's easiest to remember the acronym HOFBrINCl (pronounced "hoffbrinkle") when you're memorizing diatomic molecules. Just remember that each element's symbol is included in the acronym, not just the first letter of the element's name.
Hydrogen
Oxygen
Fluorine
Bromine
Iodine
Nitrogen
ChLorine
or use:
Never - Nitrogen
Have - Hydrogen
Fear - Fluorine
Of - Oxygen
Ice - Iodine
Cold - Chlorine
Beer - Bromine
Helium isn't part of this list, so no, it is not diatomic. It is definitely too inert to regularly form diatomic molecules with itself, although someone managed to make it bond with itself at very, very low temperatures. Even then, the two atoms were separated by an entire arm's length...

What is helium plus helium?
When two helium atoms combine, they form a molecule of helium gas (He2), which is also known as a dihelium molecule. This molecule is quite rare and unstable under normal conditions, as helium typically exists as a monoatomic gas.
How many elements does helium have?
ONE, Helium is an element, not a molecule.
How many atoms are in a molecule of helium?
A molecule of helium is composed of two helium 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.
What type of Atom or molecule is helium air in a balloon made up?
? :-(
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.
How many atoms are in a molecule of helium?
A molecule of helium is composed of two helium atoms.
Is helium a compound molecule?
No, helium is an element, not a compound molecule. It is a noble gas with the chemical symbol He and atomic number 2. Helium exists as single atoms and does not form molecules.
Is He diatomic molecule?
Helium is monoatomic.
Helium molecule has how many atoms?
Helium does not form molecules but exists as individual atoms.
What is diatonic scale and pentatonic?
a scale that is diatonic and pentatonic
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.
What type of atom or molecule helium air in balloon is made of?
? :-(

What are diatonic key signatures?
Diatonic key signatures result from the diatonic scales. There are 15 diatonic scales and each of them have a key signature which corresponds to each scale. There is a circle of fifths which shows the system on how to come across each and every diatonic key signature and scale.
