Why do pairs of electrons in the valence shell repel one another, according to the VSEPR theory?
Options
- ABecause they have opposite charges
- BBecause they have the same charges
- CBecause they are attracted to each other
- DBecause they have different energies
Correct answer
B. Because they have the same charges
Step-by-step solution
According to the VSEPR theory, pairs of electrons in the valence shell repel one another because their electron clouds are negatively charged, and like charges repel.
