What is the formula of hydronium ion and oxide ion?
The chemical formula of hydronium ion is (H3O)+.For the "oxide ion" check your spelling.
The formulas of the oxide and nitrate ions are respectively?
The formula for the oxide ion is O2-, and the formula for the nitrate ion is NO3-.
What is the oxide formula for Rb?
Since Rb forms a 1+ ion the formula for rubidium oxide is Rb2O.
What is the formula and charge for Hydronium ion and oxide?
The formula forHydronium ion isH3O+, it has a charge of +1. The formula for Hydroxide ion isOH-, and it has a charge of -1.
Is oxide polyatomic ion?
No, oxide is just an oxygen ion. The formula is just O(-2 charge), hence not a polyatomic ion. Hydoxide on the other hand is a polyatomic ion, formula being OH(-1 charge)
What is the formula for the compound formed by sodium and oxygen?
The sodium ion is Na+ and the oxide ion is O2-. Therefore the ionic compound formed between the two ions has chemical formula Na2O which is sodium oxide.
Magnesium oxide is an ionic compound represented by the formula unit?
MgO. Both the magnesium cation and the oxide anion are divalent, so that each ion neutralizes the charge of the other ion.
Why is lead IV oxide PbO2?
The IV in lead IV oxide means that the lead ion has a 4+ charge. The oxide ion has a 2- charge. The charges must cancel out to zero, so there are 2 oxide ions for every 1 lead IV ion, which is what the formula PbO2 shows.
How many protons are in an oxide ion?
There are 8 protons and 10 electrons in an oxide ion.
What is the old formula for SnO2?
It is Tin(II) oxide or Stannous oxide
What is the polyatomic ion oxide?
The polyatomic ion for oxide what is it?
Why is Fe the correct chemical formula for iron oxide?
It isn't Fe is simply iron There are three common oxides of iron. Iron II oxide, FeO (Fe2+ ion and O2- ion) Iron III oxide Fe2O3 (2 Fe3+ ions, 3 O2- ions) Iron II, III oxide Fe3O4 (2Fe 3+ ions, 1 Fe2+ ion, 4O2- ions) The formula are such that the overall charge of each oxide balances out to zero.
