Water has no helium (He) atom. Chemically water is H2O and there is no He atom present in water.
Water is chemically H2O and there is no helium (He) in water. Water has two hydrogen atoms and one oxygen atom.
A molecule of of water contain 3 atoms.
Helium is an element, so it is made of only one type of atom.
A 2 litre bottle of water contain 2 007,38.10e23 atoms.
A molecule of helium is composed of two helium atoms.
Water is chemically H2O and there is no helium (He) in water. Water has two hydrogen atoms and one oxygen atom.
A molecule of of water contain 3 atoms.
The number of helium atoms is 6,022 140 857.10e26.
Helium is an element, so it is made of only one type of atom.
Helium does not form molecules but exists as individual atoms.
He4 would contain four atoms, if it were possible for helium to combine that way.4He (which is pronounced "helium four") is a single atom, with the 4 being the number of nucleons (and thus the approximate atomic weight).
Helium has one kind of atom: helium.
The chemical formula of water is H2O; the molecule contain 3 atoms.
A 2 litre bottle of water contain 2 007,38.10e23 atoms.
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
Bromine does not contain water atoms. Water molecules are made up of two hydrogen atoms and one oxygen atom bonded together. Bromine is a chemical element with the symbol Br and does not contain water atoms.
A molecule of helium is composed of two helium atoms.
