The correct answer is: two in the first energy level, six in the second energy level
The correct answer is: two in the first energy level, six in the second energy level.
To understand why, let's look at the electron configuration of an atom. Electrons are arranged in energy levels or shells around the nucleus of an atom. The first energy level can hold a maximum of 2 electrons, while the second energy level can hold a maximum of 8 electrons.
The rule is that the first energy level is filled before electrons start filling the second energy level. So, in this case, we have 8 electrons. Since the second energy level can hold up to 8 electrons, it will be filled entirely with 6 electrons, while the remaining 2 electrons will be in the first energy level.
Hence, the correct distribution is two electrons in the first energy level and six electrons in the second energy level.
