Helium is an element, so it is made of only one type of atom.
None. Hydrogen and Helium are elements. Helium gas is made of atoms of He, there is no Hydrogen in it at all.
The element helium has an atomic number of 2, because each helium atoms contains 2 protons in its nucleus.
How many moles are there in 9.0333x1024 atoms of helium
The answer is 800,424.1026 atoms.
six photons
helium has 2 electrons
1 mole or 4 g or 0.004 kg of Helium has 6 x 1023 atoms. So, 431 kg of Helium have 65 x 1028 atoms
The number of helium atoms is 6,022 140 857.10e26.
Sugar has three kinds of atoms
Helium does not form molecules but exists as individual atoms.
Helium has one kind of atom: helium.
The answer is 8,1547.10e25.

A molecule is a group of atoms that are chemically bound together. There are many different atoms such as "H" for Hydrogen or "He" for Helium or "Na" for Sodium. Scientists represent these atoms in different sizes and colours.
