what is the electron configuration for Cl 1-
No. No two elements have the same electron configuration.
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
Cl
yes
1s22s22p63s23p5
Cl-
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
Chloride anion Cl- has the same electron configuration as Argon (its succeding noble gas) so:Cl- has 18 electrons configured like: 1s2, 2s2 2p6, 3s23p6
Cl-1.
H - Cl H has 1 electron and passes this to Cl --> H+ Cl has 7 electrones and takes 1 from H --> Cl- to obtain an octet configuration
