Question

write the electron - dot notation for the element cl.

1. none of these
2. .\ddot{cl}\cdot
3. .\ddot{cl}:
4. \ddot{cl}\cdot
5. :\ddot{cl}:
6. cl\cdot
7. \ddot{cl}\cdot
8. .\ddot{cl}:
9. cl:

Explanation:

Chlorine (Cl) has 7 valence electrons. In electron - dot notation, we place the dots around the symbol of the element to represent the valence electrons. The correct notation has the symbol 'Cl' with 7 dots around it. Option 5 has the correct arrangement with two dots on three sides and one dot on the remaining side, representing the 7 valence electrons of chlorine.

Answer:

1. :$\ddot{\text{Cl}}$:
