molecule of hydrogen gas

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 ..

Hydrogen atom has only one electron in its outermost shell, and requires one more 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. Thi..

An example of sharing of one pair of electrons (single bond). Two atoms of hydrogen share one pair of electrons to form a molecule of hydrogen (Fig. 3.4). ..

It is formed by the combination of two hydrogen atoms. Each hydrogen atom has one electron in 1s-orbital and, therefore, there are two electrons in hydrogen molecule. Both these electrons are to be accommodated in the lowest energy molecular orbital. Ac..

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..

Hydrogen Molecule (H 2 ) - It is formed by the combination of two hydrogen atoms. Each hydrogen atom has one electron in 1s-orbital and, therefore, there are two electrons in hydrogen molecule. Both these electrons are ..

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: ..

Carbon atom has four electrons in its outermost shell. Thus, it requires four more electrons to acquire a stable noble gas configuration. Each of the hydrogen atoms has only one electron in its outermost shell and requires one more electron to complete its outermost shell (to ..

A mole contains 6.023 x 10 23 particles. This is called Avogadro number. Molar volume is one mole of any gas at STP having a volume of 22.4 L. Mass of one mole of substance is called its molar mas..

Natural Gas - 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 sulphid..
