So let's have a look: Phosphides are the salts of PH3 (IUPAC: Phosphane). Deprotonization leads to P(3-). As Rubidium is Rb(+) you will need three Rb(+)s to form Rb3P. P4 + 12 Rb →(under Argon)→ 4 Rb3P. read more

Best Answer: Rb3P (3 as a subscript) rubidium has a charge of +1 and phosphorus has a charge of -3, so you need 3 Rb to balance out the -3 P. read more
