Helium exists as single atoms because it is a noble gas, therefore it has a full outer shell.

Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium is already full. Helium atoms only need 2 electrons to be full, and Helium, as an element, already has 2.
In a star atoms combine to form helium atoms?
Hydrogen- the only atom smaller
Why non metals do not exist in atomic form?
I hope I haver understood the question correctly.Metals only exist in atomic form when they are boiled.There are monatomic elements ( i.e. they are single atoms and not molecular in structure like hydrogen oxygen etc)these are the so-called noble gases, Helium, Neon, Argon, Krypton, Xenon and Radon.
How many different types of atoms are in helium?
Helium is an element, so it is made of only one type of atom.
The gas used to fill party balloons contains only helium atoms This makes helium an?
element
Why does helium exist only of single atoms?
Yes
What elements exist as single atoms not bonded to other atoms?
The group of elements that exist as separate atoms are the noble gases. Radon, neon, xenon, argon, helium, and krypton are those elements.
Atoms with only 2 protons are?
Helium Atoms
What makes up helium?
Helium is an element, and, as such, is made up of no chemical 'compounds'. In a chemical sense, Helium can be said to comprise only of single helium atoms, but, on a sub-atomic level, it comprises, as do all other atoms, of protons, electrons and neutrons.
What are the only element that exist in nature as isolated atoms?
The only such elements are the Noble Gases (He, Ne, Ar, Kr, Xe, Rn) (that is helium, neon, argon, krypton, xenon and radon)
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium is already full. Helium atoms only need 2 electrons to be full, and Helium, as an element, already has 2.
What substance is made of only one atom?
An element is a pure substance that is made up of only one kind of atom.Elements that can exist as a single atom are the noble gases in Group 18 of the periodic table.

Hydrogen- the only atom smaller
