Question

Fill in the name and empirical formula of each ionic compound that could be formed from the ions mg2+s2-,mg2+n3-,mg2+p3-,mg2+02-

CramX · Accepted Answer

Step 1: . For the ionic compound formed between Mg²+ and S²-, the empirical formula is MgS. This is because magnesium always loses two electrons to form an Mg²+ ion, and sulfur always gains two electrons to form an S²- ion. Therefore, one magnesium ion will combine with one sulfur ion to form an electrically neutral compound. Step 2: : Write the charges of the ions. Step 3: : Find the number of ions needed to balance the charges. $1 	imes (S^{2-}) = 2^-$ Since the charges are balanced, one Mg²+ ion will combine with one S²- ion. Step 4: : Write the empirical formula. Step 5: . For the ionic compound formed between Mg²+ and N³-, the empirical formula is Mg₃N₂. This is because magnesium always loses two electrons to form an Mg²+ ion, and nitrogen always gains three electrons to form an N³- ion. Therefore, three magnesium ions will combine with two nitrogen ions to form an electrically neutral compound. Step 6: : Write the charges of the ions. Step 7: : Find the number of ions needed to balance the charges. $2 	imes (N^{3-}) = 6^-$ Since the charges are balanced, three Mg²+ ions will combine with two N³- ions. Step 8: : Write the empirical formula. Step 9: . For the ionic compound formed between Mg²+ and P³-, the empirical formula is Mg₃P₂. This is because magnesium always loses two electrons to form an Mg²+ ion, and phosphorus always gains three electrons to form an P³- ion. Therefore, three magnesium ions will combine with two phosphorus ions to form an electrically neutral compound. Step 10: : Write the charges of the ions. Step 11: : Find the number of ions needed to balance the charges. $2 	imes (P^{3-}) = 6^-$ Since the charges are balanced, three Mg²+ ions will combine with two P³- ions. Step 12: : Write the empirical formula. Step 13: . For the ionic compound formed between Mg²+ and O²-, the empirical formula is MgO. This is because magnesium always loses two electrons to form an Mg²+ ion, and oxygen always gains two electrons to form an O²- ion. Therefore, one magnesium ion will combine with one oxygen ion to form an electrically neutral compound. Step 14: : Write the charges of the ions. Step 15: : Find the number of ions needed to balance the charges. $1 	imes (O^{2-}) = 2^-$ Since the charges are balanced, one Mg²+ ion will combine with one O²- ion. Step 16: : Write the empirical formula. Final Answer: The names and empirical formulas of the ionic compounds are: 1. MgS 2. Mg₃N₂ 3. Mg₃P₂ 4. MgO
