Question

question 8. state the number of electrons either lost or gained in forming each ion.
a. fe³⁺
b. cl⁻
c. s²⁻
d. na⁺
e. mg²⁺
f. p³⁻

Explanation:

Step1: Analyze \( \text{Fe}^{3+} \)

A neutral Fe atom has a certain number of electrons. The \( 3+ \) charge means Fe lost 3 electrons. So, lost, 3.

Step2: Analyze \( \text{Cl}^- \)

A neutral Cl atom. The \( 1- \) charge means Cl gained 1 electron. So, gained, 1.

Step3: Analyze \( \text{S}^{2-} \)

Neutral S atom. \( 2- \) charge means S gained 2 electrons. So, gained, 2.

Step4: Analyze \( \text{Na}^+ \)

Neutral Na atom. \( 1+ \) charge means Na lost 1 electron. So, lost, 1.

Step5: Analyze \( \text{Mg}^{2+} \)

Neutral Mg atom. \( 2+ \) charge means Mg lost 2 electrons. So, lost, 2.

Step6: Analyze \( \text{P}^{3-} \)

Neutral P atom. \( 3- \) charge means P gained 3 electrons. So, gained, 3.

Answer:

a. Lost, 3
b. Gained, 1
c. Gained, 2
d. Lost, 1
e. Lost, 2
f. Gained, 3
