What is the electron configuration of chlorine (CI)? A) 1s22s22p%3s 3p
B) 1822s22p%3s 3p
C)1s22s22p 3s24s23p3
D)15-2s 2p 3s 3p²3d3

Explanation:

In writing the electronic configuration for chlorine the first two electron will go in the 1s orbital.Since 1s can hold two electrons the next 2 electrons for chlorine go in the 2s orbital.The next 6 electrons will go in the 2p orbital.The p orbital can hold up to 6 electrons.We'll put six in the 2p orbital and then put the next 2 electron in the 3e.Since the 3s is now full.We'll move to 3p where we place remaining 5 electrons...

Thus,the electron configuration of chlorine(Cl) is
