What is ' h2o2 '???

If you mean ' H2O2' (Hydrogen Peroxide)/ Then there are 4 atoms/

Two hydrogen atoms and two oxygen atoms.

The structure is ' H-O-O-H '.

NB In chemical elemental symbols , Single letter symbols are ALWAYS a CAPITAL letter. This is the IUPAC/International recognised standard, and as shown in the Periodic Table.

Hence hydrogen is 'H' , NOT 'h' , and oxygen is 'O' , NOT 'o'.
