Iron (Fe) and Sulphur (S) are no more unstable than any other non-radioactive elements.
The compound Fe₂O₂ contains two different elements: iron (Fe) and oxygen (O). Specifically, it has two iron atoms and two oxygen atoms. Therefore, there are a total of 2 distinct elements in the compound.
4,80 moles of Fe contain 28,9062761136.10e23 atoms.

A lot!! 850 moles iron (6.022 X 10^23/1 mole Fe) = 5.12 X 10^26 atoms of iron
Fe is the chemical symbol of iron.
In 2Fe2O3, there are 2 iron (Fe) atoms and 3 oxygen (O) atoms, giving a total of 5 atoms.
There are 4 elements in FeCl3: iron (Fe) and three chlorine atoms (Cl).
Iron atoms. Fe is the symbol for iron on the table of elements.

In Fe(NO3)3 there are 3 different elements. They are iron (Fe), nitrogen (N) and oxygen (O). Now, if you are asking how many elements are in ONE MOLECULE of Fe(NO3)3, then the answer would be1Fe + 3N + 9O = 13 atoms/molecule.

There is NO such compound as 'Fe2O2'. The formula are 'Fe2O3' , and 'FeO'. In both cases the elements of combination are iron (Fe) and oxygen(O).
Since a mole of a metal is generally considered to be Avogadro's Number of atoms of the metal, the answer is 3.5 times Avogadro's Number or 2.1 X 1024 atoms, to the justified number of significant digits.

To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.
