Sub- or Superscript at Start of Formula

Question

I am using Libreoffice Math and I can't figure out how to apply subscript without having a character in front of it. I want to display a carbon nucleus.

^{6}_{12}C

Answer 1

I figured I can work around this issue this way:

""^{6}_{12}C

That does however left-align the sub- and superscript which makes it look a bit odd. Any suggestions as to how to right align it?

EDIT: Figured it out:

C lsub{12}lsup{6}
