how would i know
it is 2
4
4 because the electron configuration for nickel is
1s2, 2s2 2p6, 3s2 3p6 3d8, 4s2
principal quantum numbers: n = 1, 2, 3 and 4
3d5 4s1
You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
AnswerZero-point energy (not to be confused with Vacuum Energy) is the lowest possible energy that a quantum mechanical physical system may have and is the energy of the ground state. This energy comes from the fact that after you remove all thermal and kinetic energy from an atom there is still quantum mechanical harmonic vibration that arises due to the Heisenberg Uncertainty Principle. This energy, so far, can not be taken away from a system.
solar panels get energy from the sun and ground pumps get energy from turning water.
The energy source which Is dug out of the ground is called coal and is can be burnt to make electricity
The 2s and 2p sublevels in the second principal energy level are completely occupied in the ground state of a sodium atom.
Zinc atoms contain 30 electrons in the electron configuration 1s22s22p63s23p63d104s2. There are a total of 7 sublevels that contain electrons in an atom of zinc in the ground state.
The 3p level
5
there is only one unpaired electron in copper
the lowest energy level occupied by an electron when an atom is in its most stable energy state
Ground state configuration is nothing but the Electronic configuration of the metal in the ground state ie, the thing under normal condition. So, obviously the Ground state configuration of magnesium in [Ne] 3s2 (Atomic number 12).

In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
