N(nitrogen) = 7 electrons
3O(three oxygen) = 3* 8 electrons = 24 electrons
7 electrons + 24 electrons
= 31 electrons in NO3 ( nitrogen trioxide )
==============================
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 are 16 electrons in an O2 molecule. Each oxygen atom contributes 8 electrons, totaling 16 electrons in the molecule.

I think you mean the nitrate ion. Yes, that is a polyatomic ion with a negative charge. You write it as : NO3-
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
There are 9 atoms present in one molecule of Mg(NO3)2.

In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
There are 16 electrons in an O2 molecule. Each oxygen atom contributes 8 electrons, totaling 16 electrons in the molecule.
A NADH molecule stores 2 electrons.
A radical is a molecule or an atom with unpaired electrons and is very reactive.
Magnesium nitrate - Mg(NO3)2 - has 9 atoms in the molecule.
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
Copper nitrate molecule contain nine atoms.
