What are Non-Metals? Non-metals are elements that have properties that are the opposite of metals. They are not shiny, they are not good conductors of heat or electricity, and they are not malleable or ductile. Non-metals can be found in all three states of matter: solid, liquid, and gas. Properties of Non-Metals Non-lustrous: Non-metals do …
What is Calcium carbonate? Calcium carbonate (CaCO3) is a chemical compound that is widely found in nature. It is a white, odorless powder or crystalline solid that occurs naturally in limestone, chalk, and marble, as well as in the shells of marine organisms such as oysters and corals. Calcium carbonate is formed by the reaction …

What is Calcination? Calcination is a thermal treatment process that is used to heat solid materials at high temperatures in the absence or limited supply of air or oxygen. The process is carried out in a furnace or kiln and involves heating the material to a high temperature to cause chemical or physical transformations, often …

Chemists often rely on the periodic table of elements to explore chemical elements and their periodic properties. The table displays elements in a way that demonstrates the periodicity of their chemical properties. However, the table typically shows only the element’s symbol, which may not necessarily be its full name. While some element symbols are straightforward …

What are Valence electrons? Valence electrons are the electrons located in the outermost energy level or shell of an atom. These electrons are involved in chemical bonding and determine the reactivity and chemical properties of an element. The number of valence electrons an atom has corresponds to its position in the periodic table. In general, …
Acid rain is a form of precipitation (rain, snow, sleet, or hail) that has a higher-than-normal acidic pH level due to the presence of pollutants in the air. The primary cause of acid rain is the release of Sulfur Dioxide (SO2) and Nitrogen Oxides (NOx) into the atmosphere, usually from human activities such as burning …
