I have decided to do the write-up for Ammonia. Ammonia is a compound of nitrogen and hydrogen: Nitrogen (N) + Hydrogen (H) + Hydrogen (H) + Hydrogen (H) = Ammonia (NH3). Nitrogen and Hydrogen are not deadly, while Ammonia is rather deadly and harmful. Ammonia is mostly used in commercial cleaning products, to make things shine. Although in wide use, Ammonia is both caustic and hazardous. These solutions are irritating to the eyes and respiratory and digestive tracts, and to a lesser extent the skin. Ammonia should never be mixed into any liquid containing bleach, or a poisonous gas may result. Mixing with Chlorine-containing products or strong oxidants, for example household bleach can lead to hazardous compounds such as Chloramines (an inorganic compound). Nitrogen is a colourless, odourless, tasteless and mostly inert gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere. It was first discovered by Scottish physician Daniel Rutherford, in 1772. For Hydrogen, it is the lightest and most abundant chemical element in the universe. Hydrogen gas (H2) was first artificially produced in the early 16th century, via the mixing of metals with strong acids.
As the elements share their valence electrons, the compound bond is a covalent bond. Hydrogen atoms have one valence electron while Nitrogen atoms have five valence electron. Thus, three Hydrogen atoms is needed to bond with one nitrogen atom so that each Hydrogen atom gets the electronic configuration of Helium (two valence electron) while the Nitrogen atom gets the electronic configuration of Neon (eight valence electrons) and in the end form the compound Ammonia.
