Why is Cl written as CL2?
Answer: Explanation: We write chlorine as CL2 because chlorine is a non metallic gas . Also as chlorine is a gas it occurs in diatomic form as cl2 such as hydrogen(h2).
What is the electronic configuration of CL Class 10?
The atomic number of Chlorine (Cl) is 17. Thus its electronic configuration is $\left[ {Ne} \right]3{s^2}3{p^5}$ or $1{s^2}2{s^2}2{p^6}3{s^2}3{p^5}$. Hence the answer is option A. Note: Electrons roam the nucleus in imaginary paths called shells or orbits.
What is the configuration of 17?
If the atomic number is 17, there must be 17 protons and 17 electrons. Starting from the lowest level, we add electrons to each higher level until we have reached 17 electrons. The electron configuration becomes 1s22s22p63s23p5 .
