Iron (Fe) and Sulphur (S) are no more unstable than any other non-radioactive elements.
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.
It depends on the mass of iron. 1 mole Fe = 55.845g = 6.022 x 1023 atoms Fe
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.

Iron (Fe) and oxygen (O) are the elements that make up Fe2O2. The chemical formula Fe2O2 indicates that there are two iron atoms bonded with two oxygen atoms.
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.
