What is the Lewis structure of ClF4 plus?
Vigorouschemist Atoms and Atomic Structure Supervisor
Total electrons --> 7+42-1=48 Cl as a central atom One lone pair on Cl (on the side) 4 F's up and down and the other two on the opposite side of lone pair. F I :- Cl - F - F I F This is the best I can do with plain text.

What is the Lewis structure of NCS?

:S-C≡N: resonance with ::S=C=N:: 4 pairs either way Assuming NCS- (as above): ::S=C=N:: is better because the formal charge of -1 is on the most electronegative atom, N.

Thanks for the feedback!
