When rubidium (Rb) and phosphorus (P) bond ionically, they form the compound rubidium phosphide, and it has the formula Rb3P. This is because rubidium has a charge of +1 during bonding (because of its 1 valence electron) and phosphorus has a charge of -3 (because of its 5 valence electrons - see "octet rule.") Thus, it takes 3 rubidiums to satisfy phosphorus' need for 3 electrons. It is incorrect to call this compound "rubidium tri-phosphide," because this scenario is the only way those two elements can bond, so any prefixes would be redundant. In the naming of ionic compounds, the cation comes first, and its name is unchanged, but the anion gains the suffix "-ide."
The rubidium nitride has the chemical formula Rb3N.
RbBr is the chemical formula for rubidium bromide. Rb stands for rubidium and Br for bromine.
The chemical symbol for Rubidium-Rb Sulfate-SO4 is Rb2SO4. Rb has a charge of +1 and SO4 has a charge of -2, so in order for the charges to be balanced you need 2 Rb atoms (2 x +1) and 1 SO4 (-2) ion. +2 + -2 = 0
The chemical symbol of rubidium is Rb Rb-- atomic # 37, atomic weight 85.87
The chemical formula for the compound formed between rubidium and oxygen is rubidium oxide - Rb2O.
Rb
The rubidium nitride has the chemical formula Rb3N.
RbBr is the chemical formula for rubidium bromide. Rb stands for rubidium and Br for bromine.
The compound RbCl is ionic because it is formed between a metal (Rb) and a non-metal (Cl). Metal and non-metal combinations typically result in ionic compounds where the metal loses electrons to form cations and the non-metal gains electrons to form anions.
These are the ions and their charges: Rb+1 N-3The charges have to add up to zero, so two +1 Rb ions were added to cancel out the -3 charge of N: Rb+1 Rb+1 Rb+1 N-3Simplify: Rb3N
Rubidium is an element and its chemical symbol on the periodic table is Rb [Atomic number:37]
Since Rb forms a 1+ ion the formula for rubidium oxide is Rb2O.
Rubidium does not have a formula but a symbol: Rb.
The chemical formula for the compound formed between rubidium and oxygen is rubidium oxide - Rb2O.
The chemical symbol of rubidium is Rb Rb-- atomic # 37, atomic weight 85.87
The chemical formula for rubidium phosphite is Rb3PO3.
Rb is rubidium, O is oxygen. They will combine to form Rb2O which is called rubidium oxide.
