showing electron sharing using electron dot diagrams\nwhich electron dot diagram shows the bonding between 2 chlorine atoms?

Answer

Explanation:

Step1: Determine valence electrons of chlorine

Chlorine has 7 valence electrons.

Step2: Analyze covalent - bonding between chlorine atoms

Two chlorine atoms form a single covalent bond by sharing one pair of electrons. Each chlorine atom then has 8 valence electrons (an octet) after bonding.

Step3: Identify the correct electron - dot diagram

The correct electron - dot diagram shows a single line (representing the shared pair of electrons) between the two chlorine atoms and 3 non - bonding pairs of electrons around each chlorine atom. The correct diagram is :$\ddot{Cl}:\ddot{Cl}:$.

Answer:

The second electron - dot diagram (the one with a single line between the two $\ddot{Cl}$ atoms and 3 non - bonding pairs of electrons around each $\ddot{Cl}$ atom) shows the bonding between 2 chlorine atoms.
