What is the simplest formula of the compound containing the ions X⁴⁺ and Y^2-?
- A.
  
  XY₂
- B.
  
  X₂Y
- C.
  
  X₂Y₄
- D.
  
  X₄Y₂
Correct Answer
A. XY₂

Explanation
The simplest formula of the compound containing the ions X4+ and Y2- is XY2. This is because the charges on the ions must balance out to form a neutral compound. The 4+ charge on X cancels out with the 2- charge on Y, resulting in a balanced compound with a formula of XY2.

What are the symbols for the ions in magnesium chloride, MgCl₂?
- A.
  
  Mg⁺ and Cl⁻
- B.
  
  Mg^- and Cl⁺
- C.
  
  Mg²⁺ and Cl⁻
- D.
  
  Mg⁺ and Cl²⁻
Correct Answer
C. Mg²⁺ and Cl⁻

Explanation
The correct answer is Mg2+ and Cl− because magnesium (Mg) has a charge of +2, meaning it loses two electrons to become positively charged, while chlorine (Cl) has a charge of -1, meaning it gains one electron to become negatively charged. Therefore, when they combine to form magnesium chloride (MgCl2), magnesium has a charge of +2 and chlorine has a charge of -1.
