molecule of oxygen gas

An oxygen atom has six electrons in its valence shell. As a result, it requires 2 more electrons to achieve the nearest noble gas configuration. When two oxygen atoms share two pairs of electrons this is achieved: ..

Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it constitutes about 88% by ..

An example of sharing of two pairs of electrons (Double bond). Two atoms of oxygen share two pairs of electrons to form one molecule of oxygen (Fig. 3.5). Note :..

Oxygen Molecule (O 2 ) - Therefore, oxygen molecule has 16 electrons. In the formation of molecular orbitals, the electrons in the inner shells are expressed as KK denoting ( s 1s) 2 ( s *1s) 2 .The remaining 12 electro..

It is smallest particle (of an element or compound), which is capable of independent existence. Molecules are formed by combination of atoms. Molecules are formed by combination of atoms If the molecule is made up of atoms of the same element it is said to be homo-atom..

has no definite volume or shape is fluid is very compressible. It takes the volume and shape of the vessel in which it is kept. For example: Hydrogen and carbon dioxide All the three states of matter are inter-convertible. For example: water When water is cooled to 0 o C, it tr..

Hydrogen atom has only one electron in its outermost shell, and requires one more electron to acquire the nearest noble gas configuration of helium (He:1s 2 ). To do so, two hydrogen atoms contribute one electron each to share one pair of electrons between them. This leads to ..

It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphide. Its great advantage i..

Chlorine atom has seven valence electrons. Thus, each Cl atom requires one more electron to acquire the nearest noble gas configuration (Ar:2, 8, 8). They do this by mutual sharing of one pair of electrons as shown below...
