Question

Show formation of hydrogen molecule, state the type of bond present​

Answer 1

Answer:

The Hydrogen Molecule. When two hydrogen atoms combine to form a hydrogen molecule, H2, they do so in a way quite different from the electron transfer process we have been discussing. Two hydrogen atoms form a covalent bond by sharing their two electrons, thereby completing the K shell for each atom.

Hydrogen has one valence electron in its outermost shell. It needs one more electron to attain duplet, therefore each hydrogen atom combines with another hydrogen (H) atoms to form an H2 molecule resulting in the formation of a covalent bond.

Answer 2

Answer:

Explanation:

The elecronic confguration of hydrogen is 1s  1  .  

Thus, it contains one unpaired electron in 1s orbital.  

Two H atoms, each having one unpaired electron, combine and share their electron to form a covalent bond in which two electrons are paired.  

H⋅+H⋅→H⋅⋅H
