🌕

Symbol

 * 1) A full moon.
 * 2)  Oxygen (Daltonian symbol).

Usage notes

 * As a symbol for the full moon, this character may be displayed with a face or craters, especially as an emoji. Dalton's symbol for oxygen, on the other hand, is a simple circle. Appending the variation selector &amp;#xFE0E; will override emoji formatting. Technically the font color should be set to red, ⟨ 🌕&#xFE0E; ⟩, though it's not uncommon for that detail to be omitted. Another possibility in Unicode for Dalton's symbol is the full or medium 'white' (empty) circles $⟨◯| ◯⟩$, $⟨⚪| ⚪&#xFE0E;⟩$, depending on which matches the other element symbols in size. (Cf. the solid black symbol $⟨🌑&#xFE0E;⟩$ for carbon and the notes there for more general Unicode support.)
