How many elements is PbI2?
PbI2 has TWO(2) elements. They are ;- Pb ; Lead (Plumbum ; Latin) I ; Iodine . However, there are three (3) atoms in PbI2. Viz: - 1 x Pb(Lead) 2 x I (iodine) 1 + 2 = 3 The name of the sibstance is 'lead iodide'.
What is the formula for Pb3NO2?
The chemical formula of lead(III) nitrite is Pb(NO2)3.
What does the subscript number stand for?
The number in the subscript of a chemical formula tells the number of that atom in a molecule. For example, in H2O, the 2 tells you there are 2 hydrogen atoms in the water molecule. in C3H8, there are 3 carbon atoms and 8 hydrogen atoms as reflected by the 3 and 8 in the formula respectively.
What part of the chemical formula indicates the number of molecules or atoms involved?
The answer is 'subscript'

Is carbon being affected when there is a subscript of 3 in CO3?
NO. The subscript of 3 applies only to the oxygen (O) in CO3.
What is the charge of pb ion?
The charge of a Pb ion can vary depending on the specific ion. Commonly, lead can exist as Pb2+ or Pb4+ ions.
