Number 1
Explanation:
The first diagram represents the electron configuration of a carbon dioxide molecule.
Carbon dioxide as gaseous covalent molecule made up of two oxygen atoms and one central carbon atom:
CO₂
Carbon dioxide has linear structure with a bond angle of 180°.
In carbon dioxide, the atoms are covalent bonded.
The central atom is carbon and it joins up with two oxygen atoms.
The carbon has 4 valence electrons that goes into bonding in pairs. The oxygen atom has 6 valence electrons.
In order to complete their octet, they share their outermost electrons in the manner shown in the first diagram.
