Let's do the math.
There are currently about 120 known chemical elements. On average, each element has around three isotopes (where the nucleus has the same number of protons, but a different number of neutrons).
So a quick and dirty number would be that there are around 300-350 unique atomic nuclei. Or possibly twice that, if you consider the antimatter versions of each.
Sugar has three different types of atoms: carbon, hydrogen, and oxygen.
Ammonia has four atoms: one nitrogen atom and three hydrogen atoms.
There are 90 naturally occurring types of atoms, or elements.
Carbon can bond by covalent bonds with as many as 4 other atoms.
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
there are 100,000,0000,0000,0000 atoms in starch
No different ones, just Oxygen atoms.
