Thanks for this PR @Ak0303 - we'll soon review it and let you know if it requires any edits! Keep contributing 🎉

Have you verified yourself that these changes work? Can you put in some screenshots of all of the rendered LaTeX?

[jaladh-singhal]

Apparently every change looks fine to me!

@Ak0303 can you still cross-check if your changes are rendered correctly (like @Rodot- suggested) by rendering each class property you changed (latex_name or latex_formula) as Latex in Jupyter notebook. E.g. for Levels class in tardis/plasma/properties/atomic.py, it'll look like:

import tardis
from IPython.display import Math, display
for ln in tardis.plasma.properties.atomic.Levels.latex_name:
    display(Math(ln))

The output should be exact same for your modified code and current code at tardis.
