@Bacracks70 I would recommend to use some text expansion tool (there are quite a few depending on your OS) and define e.g. aang to yield the Å character. This way you can conveniently insert Angstrom in normal text.
If you need to use Angstrom in LaTeX equations, you should put it in the argument of the \pu{...} command (which stands for physical unit):
$$r = \pu{0.2 Å}$$
This would render as:
