If a chemical symbol has a subscript associated with it, there are multiple atoms of that element in the compound. Unless they are part of a polyatomic ion, each atom of that element is an individual ion. For example, iron (III) sulfate is written Fe2(SO4)3. The +3 oxidation state of...
For example, to find the molecular mass of NH3, the first step is to look up the atomic masses of nitrogen (N) and hydrogen (H). H = 1.00794 N = 14.0067 Next, multiply the atomic mass of each atom by the number of atoms in the compound. There is one nitrogen atom (no subscript ...
Describe how to find the mass of an atom. Mass of the Atom: Mass of the atom is the addition of the neutron and proton that are found inside the nucleus of the atom. The SI unit of the mass of the atoms is a kilogram, but it is usually represented in a.m.u(atomic mass unit)...
The main chain usually refers to the parent chain of an organic compound. The basic thing to consider for the main chain is the longest carbon chain or a cyclic structure present in the organic compound. We need to take note and look into the parent chain/main chain because it is...
Atoms form molecules and compounds by sharing electrons to create chemical bonds. Understanding the nature of this bonding begins by knowing the number of electrons associated with each atom. With the information from a periodic table of the elements, and some straightforward arithmetic, you can calc...

How to Find Oxidation Number The oxidation number of an atom in an ion or compound can be determined using the above rules. Let us look at a few examples [1-6]. 1. Sulfuric Acid (H2SO4) The oxidation number of hydrogen (H) and oxygen (O) are +1 and -2, respectively. Sulfuric ...
It consists of two plates with a voltage across them, along with a radioactive source of ionizing radiation, like this: The alpha particles generated by the americium have the following property: They ionize the oxygen and nitrogen atoms of the air in the chamber. To "ionize" means to "...
Then, you require considering compounds with more complicated formulas. So, if you’re working with a compound, having more complicated subscripts, you need to consider the overall number of atoms in this compound. Finally, you should get down to calculation. Utilize the molar mass in various ...
If you want to see a hologram, you don't have to look much farther than your wallet. There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of...
