Answer
Explanation:
Step1: Determine charge - balance principle
In an ionic compound, the total positive charge equals the total negative charge. Barium ion ($\text{Ba}^{2 + }$) has a charge of +2 and phosphorus ion ($\text{P}^{3 - }$) has a charge of - 3.
Step2: Find the least - common multiple of charges
The least - common multiple of 2 and 3 is 6.
Step3: Calculate number of ions
To get a total positive charge of +6, we need 3 $\text{Ba}^{2+}$ ions ($3\times2 = 6$). To get a total negative charge of - 6, we need 2 $\text{P}^{3 - }$ ions ($2\times3=6$).
Step4: Write the chemical formula
The chemical formula is written with the cation (positive ion) first and the anion (negative ion) second. So the formula is $\text{Ba}_3\text{P}_2$.
Answer:
Ba3P2
