An amphoteric oxide is a type of oxide that can act as both an acid and a base. This means it can react with both acids and bases, either accepting or donating protons (H⁺ ions) depending on the pH of the solution. Amphoteric oxides exhibit this dual behavior because they have both acidic and basic properties. Aluminum oxide (Al₂O₃) and zinc oxide (ZnO) are examples of common amphoteric oxides.

Metals are electropositive elements because they tend to lose electrons easily. In chemical reactions, metals readily give away their outer electrons to form positive ions, making them good conductors of electricity and heat. This electron loss leads to the formation of cations, which contribute to the electropositive nature of metals.

1 volt = 1 joule / 1 coulomb

This equation represents the definition of voltage (in volts). It states that one volt is equal to one joule of energy per one coulomb of charge. Voltage measures the electric potential difference between two points and is a fundamental concept in electrical physics.
