Why only H2 exists and molecules like H3, H4 etc. are not formed? |
|
Answer» Two atoms of hydrogen combine to form a molecule. Each hydrogen atom has one electron in its 1s orbital. When the two H atoms come closer to each other their 1s orbitals overlap each other, and both the available electrons are used up in forming a bond between two H-atoms. Since there is no other electron left, the hydrogen molecule (H2) has no capacity for bonding with more hydrogen atoms. Therefore, only H2 exists and molecules like H3, H4 etc are not formed. |
