Explanation:
Electronic Configuration of Element A:
- The electronic configuration of element A is 2, 8, 6. This means that it has 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third energy level.
Stable Configuration:
- In order to have a stable electronic configuration, element A needs to have a fully filled outermost energy level.
- The outermost energy level of element A is the third energy level, which can hold a maximum of 8 electrons.
Number of Electrons Needed:
- Element A already has 6 electrons in its third energy level, so it needs 2 more electrons to have a stable configuration.
- Therefore, it requires 2 more electrons to have a stable configuration.
Therefore, the correct answer is option 'A) 2'.
