KSCN. Tools. NaOH. This is because 2 lots of 1- charges make up a 2- charge. The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s 2. Ba_3N_2 Barium is an alkaline earth metal, and forms Ba^(2+) ions; nitrogen is from Group 15, and can form nitride ions, N^(3-). Ag 2 S. Ba 3 N 2. PbCl 2. Zn(C 2 H 3 O … Look up the name and charge for nitrate on the Common Ion Table; Balance the charges so the total charge on the compound is zero. Write the element symbol and ionic charge for Barium. Check . Select the answer from the drop-down-menu. This 2- charge cancels out the 2+ charge in the Barium, thus giving a stable molecule. Ionic Formula.

The salt that forms will be electrostatically neutral, so a formula of Ba_3N_2. Name. Fe 2 O 3. NH 4 OH. Cation: Barium (Ba with a charge of 2+) Anion: Nitrate (NO3 with a charge of 1-) The formula will be Ba(NO3)2. When you are finished, press "Check" to check your answers. For Barium nitrate we have a metal (Barium) and then a polyatomic ion (when you see a name ending in ate it is likely an ion). Ca 3 (PO 4) 2. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. 2 Ba2+ N3-barium nitride 8 Ga 2 S 3 Ga3+ S2-gallium sufide 9 Li 3 P Li1+ P3-lithium phosphide 10 Na 2 S Na1+ S2-sodium sulfide 11 Ag 2 O Ag1+ O2-silver oxide 12 CaF 2 Ca2+ F1-calcium flouride .
