How covalent bond is formed in carbon dioxide:
- Atom oxygen has 6 valence electrons and 2.6 electron arrangement.
- Each atom oxygen needs 2 more electrons to fill the valence shell in order to achieve a stable octet electron arrangement. Hence, each atom oxygen contributes 2 electrons for sharing.
- Atom carbon has 4 valence electrons and 2.4 electron arrangement.
- Each atom carbon needs 4 more electrons to fill the valence shell in order to achieve a stable octet electron arrangement. Hence, each atom carbon contributes 4 electrons for sharing.
- One atom carbon shares 4 electrons with two atom oxygen to achieve a stable octet electron arrangement.
