In one molecule H2O you'll find two ATOMs hydrogen (H atoms), as indicated by the subscripted 2 .
(You would do better by using capitals for elements.)
The chemical formula of water is H2O. It implies it is made of three atoms.
A drop of water typically consists of 2 hydrogen atoms and 1 oxygen atom. This is represented by the chemical formula H2O.
The formula CaCO3 represents 5 atoms: 1 calcium atom, 1 carbon atom, and 3 oxygen atoms.
The formula for cuprous oxide is Cu2O. The formula for copper is just Cu, although many copper items are not pure copper.
Oxygen is always given the symbol O In chemical compounds there can be many oxygen atoms. The compound has the formula not oxygen. Example Water is the compound, its formula is H2O Sodium sulfate is the compound, its formula is H2SO4
The chemical formula of water is H2O. It implies it is made of three atoms.
A chemical formula is the representation of a molecule of a chemical compound; all the atoms from the molecule of this compound need to be represented in the formula.
A drop of water typically consists of 2 hydrogen atoms and 1 oxygen atom. This is represented by the chemical formula H2O.
There are 5 atoms represented in the formula CaCO3: 1 calcium (Ca) atom, 1 carbon (C) atom, and 3 oxygen (O) atoms.
