Correct Answer

B. ऋण दो मूल आवेश / Minus two elementary charges

Step 1

Concept

Initial charge is minus seven elementary charges.

Step 2

Why this answer is correct

Losing five electrons gives a plus five elementary charge change.

Step 3

Exam Tip

Minus seven plus plus five gives minus two elementary charges. चरण 1: प्रारंभिक आवेश ऋण सात मूल आवेश है। चरण 2: पांच इलेक्ट्रॉन खोने से धन पांच मूल आवेश का परिवर्तन होगा। चरण 3: ऋण सात और धन पांच का योग ऋण दो मूल आवेश है।
