Why does oxygen exist as gas?

Due to this reason the intermolecular forces present in oxygen are weak van der Waals forces. The main reason behind this is the small size and high electron density in it which tends to repel the other oxygen O2 molecules. As a result of these reasons oxygen exists as gas.

Why oxygen exists as O2 while sulphur exists as S8?

Oxygen molecule has the formula O_(2) while sulphur is S_(8). In the molecule of oxygen, the two oxygen atoms are linked to each other by double bond (O=O) i.e., one sigma bond formed by axial overlap and one pi-bond formed as a result of sidewise overlap. Therefore, oxygen exists as a diatomic molecule.

Why does oxygen exist as a gas at room temperature?

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.

Why oxygen is a gas Class 12?

They have low densities and can be compressed easily. As the property of gases having no shape and volume, oxygen do not have a fixed shape or volume. Oxygen flows from areas of higher to lower concentrations. Hence for these reasons oxygen remains as gas.

Can oxygen exist as a solid?

Oxygen becomes solid at temperatures below -218.79℃. In both its liquid and solid states, the substances are clear with a light sky-blue colour. Liquid oxygen is a physical form of oxygen.

Why is oxygen and sulfur in the same group?

Sulfur forms many compounds that are analogues of Oxygen compounds. So, Oxygen and Sulphur are kept in the same group, the reason is a similar number of electrons in the outermost shell.

Why is oxygen diatomic and sulphur?

Why oxygen molecule is diatomic whereas sulphur molecules is octa atomic? Oxygen atom is small and hence capable of forming pπ-pπ multiple bond and thus exists as O2. On the other hand, due to large size, sulphur does not form pπ-pπ multiple bond and form S8 rings.

Why does oxygen exist O2?

The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.

Is sulfur a gas at room temperature?

Sulfur is a chemical element with symbol S and atomic number 16. Classified as a nonmetal, Sulfur is a solid at room temperature.

Why oxygen is diatomic while sulphur is Octaatomic?

Why sulphur does not exist as diatomic in nature?

Because of its larger size, compared with oxygen, the sulphur atom tends not to form double bonds with other sulphur atoms. S8 is a cyclic, non-planar (to avoid bond strain) molecule.

Why oxygen shows Catenation Behaviour less than sulphur?

Due to small size of oxygen atom there is greater 1p-bp repulsion in O – O, resulting in weakening of O – O bond more than in S-S bond. Therefore the tendency of catenation in oxygen is lower than sulphur.
