a hydrogen molecule

Hydrogen atom has one electron in its electron shell. It needs one more electron to attain a duplet. A molecule of hydrogen is formed by the sharing of one pair of electrons between two hydrogen atoms as shown below:..

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..

This is formed by the combination of hydrogen atom containing one electron and hydrogen ion having no electron. Therefore, this ion has only one electron. ..

The carbon atom in HCN, shares one electron-pair with hydrogen, thus forming a single covalent bond with H atom. The C atom shares three electron pairs with N atom to form a triple bond between C and N. The combining of atoms and Lewis structure of HCN molecule is giv..

This is formed by the combination of hydrogen atom containing one electron and hydrogen ion having no electron. Therefore, this ion has only one electron. fig 1.17 - Molecular orbital energy level diagram for H 2 + ion The positive value of bond order indicat..

Nitrogen atom has five electrons in its valence shell. Thus, it requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below: ..

Two hydrogen atoms mutually share one electron each with an atom of oxygen to form a water molecule (Fig. 3.8). Note ..

Three hydrogen atoms mutually share one pair of electrons each with a nitrogen atom to form a molecule of ammonia (Fig. 3.10). Note ..
