Question

how many electrons are represented in 2 lines (double bond)?
4 electrons
2 electrons
6 electrons

Explanation:

Step1: Recall bond - electron relationship

Each line in a bond represents 2 electrons.

Step2: Calculate electrons in double - bond

For a double bond (2 lines), we multiply the number of lines by 2. So, $2\times2 = 4$.

Answer:

4 electrons
