The principal energy level that contains electrons with the lowest energy is the first energy level (n=1). This level is closest to the nucleus and has the least amount of energy associated with its electrons.
Electrons located in the innermost energy levels (such as the 1s level) have the lowest energy. These energy levels are closest to the nucleus and are filled first in an atom according to the aufbau principle.
there are eight electrons.
Magnesium (Mg) has two electrons in it's lowest (s) orbital.
The electron closest to the nucleus has the lowest energy level. Since electrons are attracted to the nucleus, it takes energy to make them orbit at a greater distance (and even more energy to remove them from orbit entirely).
The term "1s" typically refers to the orbital energy level in an atom. It represents the first energy level or shell where electrons are located. In the 1s orbital, electrons are closest to the nucleus and have the lowest energy.

the lowest energy level to allow f orbitals is the fourth energy level
Generally, the lowest open one.
Two electrons can be housed in the first energy level.
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
