Question

part 3 (0.5 point) lithium combined with nitrogen is... formula: name: part 4 (0.5 point) aluminum combined with chlorine is... formula: name:

Explanation:

Step1: Determine lithium and nitrogen ions

Lithium (Li) forms $Li^+$ ion with a +1 charge, nitrogen (N) forms $N^{3 -}$ ion with a - 3 charge.

Step2: Write the formula

To balance the charges, we need 3 lithium ions for 1 nitrogen ion. The formula is $Li_3N$.

Step3: Name the compound

The name of the compound is lithium nitride.

Step4: Determine aluminum and chlorine ions

Aluminum (Al) forms $Al^{3+}$ ion with a +3 charge, chlorine (Cl) forms $Cl^-$ ion with a - 1 charge.

Step5: Write the formula

To balance the charges, we need 1 aluminum ion and 3 chlorine ions. The formula is $AlCl_3$.

Step6: Name the compound

The name of the compound is aluminum chloride.

Answer:

Part 3:
formula: $Li_3N$
name: lithium nitride
Part 4:
formula: $AlCl_3$
name: aluminum chloride
