Specify the number of oxygen atoms (red) represented in each set of molecular models:
Here, we are going to calculate the number of oxygen atoms present in each set of molecular models.
Atom is the smallest tiny representation of an atom.
Chemical formula is the representation of the number of atoms present in the molecule or molecular compound .
It is model of Carbon dioxide (CO2).
Total number of oxygen atoms in (a) = 2 x 5 =10
