The maximum number of electrons that can occupy a specific energy level can be found using the following formula: Electron Capacity = 2n2. The variable n represents the Principal Quantum Number, the number of the energy level in question. Since the M-shell belongs to 3rd energy level, its electron capacity = 2 × 32 = 18

Correct Option: C

Galvanization is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. The term is derived from the name of Italian scientist Luigi Galvani. Although galvanization can be done with electrochemical and electro-deposition processes, the most common method in current use is hot-dip galvanization, in which steel parts are submerged in a bath of molten zinc.

Magnetite is a mineral, one of the two common naturally occurring iron oxides (chemical formula Fe₃O₄
). It is the most magnetic of all the naturally occurring minerals on Earth. The chemical IUPAC name of magnetite is iron oxide and the common chemical name is ferrous-ferric oxide

Aerated water is, correctly speaking, water to which air is added. So aerated water is any water artificially impregnated with a large amount of gas (as carbon dioxide). The term is, however, frequently applied to carbonated water.
