Detailed explanation-1: -The energy levels of an atom cannot all hold the same number of electrons. The first level can hold a maximum of two electrons, while the second and third can hold up to eight and eighteen electrons each.
Detailed explanation-2: -Answer and Explanation: The maximum number of electrons in the first energy level is 2. The maximum number of electrons in the second energy level is 8. The maximum number of electrons in the third energy level is 18.
Detailed explanation-3: -Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
Detailed explanation-4: -What is the 2 8 8 18 rule in chemistry? Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
Detailed explanation-5: -The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons.
