WebJan 25, 2024 · Across a period, the basic nature of oxides gradually decreases, and acidic nature gradually increases. If the same element forms many oxides, acidic nature increases with an increase in the number of oxygen atoms forming the oxide. The most basic oxide is caesium oxide. Caesium hydroxide is the strongest base. WebOxides are binary compounds formed by the reaction of oxygen with other elements. Oxygen is highly reactive in nature. They react with metals and non-metals to form oxides. What are Oxides? The classification of oxides is done into neutral, amphoteric and basic or acidic based on their acid-base characteristics.
