Which of the following is correct about the electrons in the 1s orbital? They
Answer Details
The correct option about the electrons in the 1s orbital is that they are closest to the nucleus. The 1s orbital is the lowest energy level in an atom, and it is located closest to the nucleus, which has a positive charge. The closer an electron is to the nucleus, the stronger the attractive force between them, so electrons in the 1s orbital are more strongly attracted to the nucleus than those in other orbitals. This makes them harder to remove from the atom, and they require more energy to be ionized. The other options are not correct: electrons in the 1s orbital do not necessarily have the same spin, they are not easier to remove than those in the 2p orbital, they do not have the same energy as those in the 2s orbital, and they do not have different magnetic quantum numbers.
