At least two.
The number of atoms required to form a molecule depends on the specific molecule. Covalent molecules can range from 2 atoms (e.g., H2) to thousands of atoms (e.g., proteins). Ionic compounds consist of positively and negatively charged ions arranged in a structure, not individual molecules.
three!
If you are asking how many atoms of Hydrogen are in that molecule, the answer is 5, hence the "H5". If you are asking how many molecules are needed in the reaction that results in C3H5, it could be 5 or more depending on the molecules and energies involved.
Two atoms of sodium are required to react with one molecule of Br2 to form sodium bromide. Therefore, to completely react with 5 molecules of Br2, you would need 10 atoms of sodium.
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
One molecule of Oxygen contains two atoms.
There are two atoms of Hydrogen in the molecule.
Helium does not form molecules but exists as individual atoms.
There are three atoms in a molecule of water. One oxygen atom and 2 hydrogen atoms. The simplified form for the molecule of water is H2O which is a coded form for the 2 hydrogen and 1 oxygen atoms that make up the molecule.
A sulfur molecule contains many sulfur atoms. These atoms combined together to form sulfur molecule i.e. S8.
A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
If you are asking how many atoms of Hydrogen are in that molecule, the answer is 5, hence the "H5". If you are asking how many molecules are needed in the reaction that results in C3H5, it could be 5 or more depending on the molecules and energies involved.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
