How are molecules and poly-atomic ions unlike?
A molecule is neutral, an ion has an electrical charge.
Is potassium iodide a poly atomic ion?
No, potassium iodide is a compound composed of the monatomic ion K+ (potassium cation) and the monatomic ion I- (iodide anion). It is not a polyatomic ion.
The minimum number of elements found in a polyatomic ion is what?
Two or more for POLY atomics, or in the other case it were a 'mono' atomic ion (= ONE)
What is atomic mass of gold ion?
The atomic mass of a gold ion is the same as the atomic mass of a gold atom, which is approximately 196.97 atomic mass units. This value is calculated based on the average mass of all isotopes of gold and takes into account the abundance of each isotope.
Do molecule have charge?
No. Molecules do not have charge. Ions have a charge. If a compound is has more than one atom and a charge, then it is a poly-atomic ion, not a molecule.
What is the charge of the ion that phosphorus would form?
The phosphide ion, meaning phosphorous by itself not bound up in a poly-atomic ion, has a charge of -3 in ionic compounds.
How many protons and electrons are in the ion gold(III)?
Gold(III) refers to a gold ion with a +3 charge, meaning it has lost three electrons. The atomic number of gold (Au) is 79, which indicates it has 79 protons. Therefore, in the gold(III) ion, there are 79 protons and 76 electrons.
What is the correct formula for the carbonate polyatomic ion?
Acetate ion is CH3C00-, C2H3O2-. It is the conjugate base of acetic acid, CH3COOH
What is the symbol for cupric sulfate?
Permanganate is a poly atomic ion, not an element. It contains two elements: manganese (Mn) and oxygen (O). The formula of the permanganate ion is MnO4-
Does the atomic number changes when an ion is formed?
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.
What is the ion for gold?
The most common ion for gold is Au3+, known as the auric ion.
Which poly-atomic ion forms a neutral compound when combined with a group IA monotonic ion in a 11 ratio?
The polyatomic ion that forms a neutral compound when combined with a Group IA monatomic ion in a 1:1 ratio is the nitrate ion (NO₃⁻). When the nitrate ion pairs with a Group IA cation, such as sodium (Na⁺), they create a neutral compound like sodium nitrate (NaNO₃). This 1:1 ratio ensures that the positive charge of the monatomic ion balances the negative charge of the polyatomic ion.
