Atomic number is a property of an atom (An Element) and not a chemical compound. Water is a compound and thus it can not have any atomic number.
Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.

What is the atomic number for H2O?
H2O is a molecule composed of two hydrogen atoms and one oxygen atom. Each hydrogen atom has an atomic number of 1, and the oxygen atom has an atomic number of 8. Therefore, the atomic number for H2O is 8.
What is the atomic mass and number for H2O?
The atomic mass of H2O is 18.01528amu. Each hydrogen atom has a mass of 1.00794amu and the oxygen atom has a mass of 15.9994amu. There is not atomic number for H2O, as it is a compound, not an element. H: 2 x 1.00794amu = 2.01588amu O: 1 x 15.9994amu = 15.9994amu Total = 18.01528amu
What you the mass number of H2o?
The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.
What is the mass number of water?
Elements, as listed on the periodic table have atomic numbers, whereas molecules, like water (H2O) have molecular weight, which is the sum of all of the atomic masses of the atoms in a molecule. Each of the components of H2O have an atomic number: Hydrogen has an atomic number of 1 (because it has 1 proton); Oxygen has an atomic number of 8 (it has 8 protons). So, if a person were to try to assign an atomic 'number' to H2O they would likely come up with 2 x 1 (for the 2Hydrogens) + 8 (for the Oxygen) = 10! Now, because an atomic 'number' indicates an element on the periodic table, we'd have to look at the periodic table...and find that 10 is Ne (Neon). As you can see, this would be completely wrong as water is NOT neon! So, water does not have an atomic number. It does, however have a molecular weight! The molecular weight of H2O can be calculated by referring to the periodic table, where we would find that Hydrogen has a weight of 1.0079 grams per mol and Oxygen has an atomic weight of 15.9994 grams per mol. The molecular weight of H2O can be calculated by figuring out how many of each atom is in the molecule, and then multiplying each by it's weight. So: Hydrogen has an atomic weight of 1.0079 and there are two of them in H2O: 1.0079 x 2 = 2.0158 grams per mole Oxygen has an atomic weight of 15.9994 and there is one in H20: 15.9994 x 1 = 15.9994 grams per mole Add them up! 2.0158 + 15.9994 = 18.0152 grams per mole H20 has a molecular 'weight' of 18.152 grams!
What is the atomic formula for h2o?
The atomic formula for water (H2O) is composed of two hydrogen atoms and one oxygen atom.
What is the atomic molecule of water?
The atomic molecule of water is H2O. It consists of two hydrogen atoms bonded to one oxygen atom.
How many moles are there in 235 grams of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O=18.0 grams235 grams H2O / (18.0 grams) = 13.1 moles H2O
