[Solved] Can't write Ni_3 (PO_4)_2

Postby debaser » Sat Oct 04, 2014 8:46 am

I need to write the formula for Nickel(II) phosphate for an online class. When I type it out the Ni shows up as ? . So my formula ends up ?3(PO_4)_2. What can I do?

Hi and welcome to the forum!

Use: "Ni"_3 (PO_4)_2
The Ni string may be used for a special feature in Math, requesting other arguments.

Literal text (quoted) and variable names (unquoted) may have different formatting, so better quote all element names in the formula.
"Ni"_3 ("PO"_4)_2

The default setting for Math is to use plain characters for literal text, and italics for variable names.
