<p>Name: ______Class: ______Date: ______</p><p>Ions</p><p>How many protons, neutrons and electrons are present in each of the following atoms or ions?</p><p>Atom/Ion Protons Neutrons Electrons 24Mg 24Mg2+ 59Co2+ 59Co3+ 59Co 79Se 79Se2- 63Ni 59Ni2+</p><p>Common Polyatomic Ions</p><p>Write the names and charges of these ions/atoms.</p><p>1. Phosphate Ion 10. Nitride Ion 2. Chlorine Atom 11. Sulfate Ion 3. Sulfite Ion 12. Sulfide Ion 4. Acetate Ion 13. Ammonium Ion 5. Sulfur Atom 14. Nitrite Ion 6. Carbonate Ion 15. Chlorate Ion 7.

Each and every compound has a positive part and a negative part. The positive part comes FIRST and the negative part comes LAST.</p><p>Procedure: 1. Write the chemical symbol of the positive part of the compound first and then write the chemical symbol for the negative part of the compound. 2. Write the charge (oxidation number) for both the positive and the negative part of the compound. 3. Since all compounds are NEUTRAL, the charges of the chemical formula must be balanced. USE SUBSCRIPTS ONLY!! The total charge of the positive part of the compound MUST EQUAL the total charge of the negative part of the compound so the over all charge is NEUTRAL.</p><p>When more than one POLYATOMIC ION is needed—use PARENTHESES. NEVER, EVER, NEVER, use parenthesis with MONATOMIC IONS!!!!!!!!!! Write the formula for each of the following ionic compounds:</p><p> a. Sodium dihydrogen phosphate f. Ammonium hydrogen sulfate b.
