What is an Inorganic Compound?

Inorganic compounds are substances formed by various chemical elements. Unlike organic compounds, the main component in inorganic compounds is not always carbon. Water is the most abundant inorganic compound. Almost all known elements can be involved in the formation of inorganic compounds.

History of Inorganic Chemistry

• The beginnings of inorganic chemistry trace back to the history of civilized man. Since the early metal ages, people have been devoted to understanding the minerals in deposits and how they react under certain conditions.
• Later, during the Middle Ages and Renaissance, significant knowledge was gained through the pursuit of a reaction that could lead to gold from other metals. This practice was known

Chemical Bonding

Chemical bonding is the attractive force that holds atoms together in atomic groupings. Atoms that achieve stability by sharing electrons with other atoms are linked by a covalent bond.

Water

Water remains liquid at room temperature, whereas other similar substances are immediately converted into gases.

• The density of water increases to abnormally high temperatures from 0 to 4°C, reaching a maximum value of 1000 kg/m³. Above or below these temperatures, water expands, and its density decreases.
• In its solid state, water floats on liquid water, contrary to what occurs with other substances.
• Water is an excellent heat storage medium. Its resistance to increasing or decreasing its temperature is higher than that of other liquids or
