Question

nitrogen ion with 10 electrons
express your answer as a signed integer. for example, 2+ or 1-.

part d
silicon ion with 18 electrons
express your answer as a signed integer. for example, 2+ or 1-.

Explanation:

Step1: Find nitrogen's proton count

Nitrogen (N) has an atomic number of 7, so it has 7 protons: $p^+ = 7$

Step2: Calculate nitrogen ion charge

Charge = protons - electrons: $7 - 10 = -3$

Step3: Find silicon's proton count

Silicon (Si) has an atomic number of 14, so it has 14 protons: $p^+ = 14$

Step4: Calculate silicon ion charge

Charge = protons - electrons: $14 - 18 = -4$

Answer:

Part C: $3-$
Part D: $4-$
