The Correct Answer and Explanation is :
To form stable ionic compounds, atoms transfer electrons to achieve full outer electron shells, resulting in positively charged cations and negatively charged anions. Below are the combinations provided, along with their ionic charges and chemical formulas:
- Lithium and Fluorine:
- Ionic Charges: Lithium (Li) loses one electron to form a cation with a +1 charge (Li⁺). Fluorine (F) gains one electron to form an anion with a -1 charge (F⁻).
- Chemical Formula: Li⁺ and F⁻ combine in a 1:1 ratio to form lithium fluoride (LiF).
- Beryllium and Oxygen:
- Ionic Charges: Beryllium (Be) loses two electrons to form a cation with a +2 charge (Be²⁺). Oxygen (O) gains two electrons to form an anion with a -2 charge (O²⁻).
- Chemical Formula: Be²⁺ and O²⁻ combine in a 1:1 ratio to form beryllium oxide (BeO).
- Magnesium and Fluorine:
- Ionic Charges: Magnesium (Mg) loses two electrons to form a cation with a +2 charge (Mg²⁺). Fluorine (F) gains one electron to form an anion with a -1 charge (F⁻).
- Chemical Formula: To balance the charges, two fluoride ions are needed for each magnesium ion, resulting in magnesium fluoride (MgF₂).
- Aluminum and Chlorine:
- Ionic Charges: Aluminum (Al) loses three electrons to form a cation with a +3 charge (Al³⁺). Chlorine (Cl) gains one electron to form an anion with a -1 charge (Cl⁻).
- Chemical Formula: To balance the charges, three chloride ions are needed for each aluminum ion, resulting in aluminum chloride (AlCl₃).
- Beryllium and Nitrogen:
- Ionic Charges: Beryllium (Be) loses two electrons to form a cation with a +2 charge (Be²⁺). Nitrogen (N) gains three electrons to form an anion with a -3 charge (N³⁻).
- Chemical Formula: To balance the charges, three beryllium ions are needed for every two nitrogen ions, resulting in beryllium nitride (Be₃N₂).
These compounds are formed through the transfer of electrons, leading to the formation of ions that are held together by strong electrostatic forces in a lattice structure. The resulting compounds are electrically neutral, with the total positive charge equal to the total negative charge.
