Electron Configuration: The Key to Chemical Behavior

The electron configuration of an atom describes how its electrons are arranged in different energy levels (shells) and sublevels (orbitals)

Neutralization is a chemical reaction in which an acid and a base react to form water and a salt. This

Bases are substances that release hydroxide ions (OH⁻) when dissolved in water, making the solution alkaline. These OH⁻ ions are

Acids are substances that release hydrogen ions (H⁺) when dissolved in aqueous solution. These free H⁺ ions, also called protons,

Salt, or sodium chloride (NaCl), is a well-known ionic compound formed by the chemical reaction between the metal sodium (Na)

Gold (Au) is a highly unreactive element and is classified as a noble metal due to its remarkable resistance to

A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy—the minimum amount of energy

The law of conservation of mass states that in any chemical reaction, mass is neither created nor destroyed. This means

Endothermic reactions are chemical processes that absorb heat energy from their surroundings, resulting in a drop in temperature around the

Exothermic reactions are chemical reactions that release heat energy into their surroundings. This results in an increase in temperature of
