Physical And Chemical Properties Of Oxygen. A physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter). It is moderately soluble in water.
The lone pairs are closer to the oxygen atom than the electrons sigma bonded to the hydrogens, so they require more space. The water has a neutral effect. Chemical properties of oxygen at standard temperature and pressure (stp), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula o 2.
Aluminum properties are so distinct that, it is being widely used in industry, household, medicine etc.
It is smooth and soft to touch. The lone pairs are closer to the oxygen atom than the electrons sigma bonded to the hydrogens, so they require more space. Other forms of solid oxygen appear red, black, and metallic. The solid and liquid types are a light blue colour.
