The formula for lead (II) nitrate is Pb(NO3)2.
Sodium Nitrate NaNO3 (subscript) for sodium ion Na+ and and nitrate ion NO3- combine to form this compound
Fe(NO3)3
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
No. Numerical subscripts must be whole numbers, so you need to double each subscript and you will get N2H4O3. However, ammonium nitrate is an ionic compound and the formula includes both ions separately. The ammonium ion has the formula NH4+, and the nitrate ion has the formula NO3-. When you write a formula for an ionic compound, the positively charged ion is written first, and the negatively charged ion is written second. So the formula for ammonium nitrate is NH4NO3. Also, the numberical subscript 1 is never written. If there is no subscript written, it is understood to be 1.
The element beryllium has an atomic number of four. All atoms of this Group 2 metal, regardless of which isotope we might consider, have four protons in their nucleus. And all beryllium atoms have a +4 nuclear charge.
