I don't know what the "2" is, but NH4+ is the formula for the ammonium ion. It has a charge of 1+.
NH2-
Formula: (NH4)2C2O4
That would be ammonium carbonate (NH4)2CO3
The polyatomic ion is the ammonium ion, NH4^+
Yes. The ammonium ion has a formula of NH4+ and has a positive charge so it is a cation.
Ammonium ion has a single positive charge. + ie NH4
I don't know what the "2" is, but NH4+ is the formula for the ammonium ion. It has a charge of 1+.
The ammonium ion is (NH4)+.
The chemical formula of ammonium is (NH4)+.
Ammonium is an ion not an element; the chemical formula is (NH4)+.
The chemical formula of the ammonium ion is NH4+. Formula mass of NH4+ = 14.0 + 4(1.0) = 18.0
Those are chemical formulas. NH4 is the ammonium polyatomic ion, and PO4 is the phosphate polyatomic ion. Ammonium has a +1 charge and phosphate has a -3 charge.
The ammonium ion forms when an ammonia molecule (NH3) takes a hydrogen ion (H+) either from an acid or from water. The positive charge on the hydrogen ion is taken over into the new ammonium ion.
NH4+The ammonium ion is (NH4)+.
NH4+
NH2-
