Oxygen is a non-metal element, so it is considered a "hard" element. In chemistry, "hardness" generally refers to the ability of an element to form bonds with other elements. Oxygen typically forms strong covalent bonds with other elements, contributing to its classification as a "hard" element.
Oxygen itself is a gas, so it doesn't have a physical texture like being soft or hard. It is essential for life and makes up about 21% of Earth's atmosphere.
Sodium is considered a soft metal. It is malleable and easily cut with a knife.
Soap can be both hard and soft, depending on the ingredients used in its formulation. Traditional bar soaps are usually hard, while liquid soaps tend to be soft. The hardness of soap is often influenced by the amount of oils and fats in the recipe.
Hard nucleophiles are small, highly charged ions with localized electron density, while soft nucleophiles are larger, less charged ions with more diffuse electron density. Hard nucleophiles prefer to react with electrophiles that are also hard, while soft nucleophiles prefer soft electrophiles. This selectivity is known as the hard and soft acid-base theory. The reactivity of nucleophiles in chemical reactions is influenced by their size, charge, and electron density, with hard nucleophiles typically reacting faster with hard electrophiles, and soft nucleophiles reacting faster with soft electrophiles.
Neon is niether hard or soft because it is a noble gas.
Oxygen is a gas.so,it is not hard or soft.
