The maximum number of electrons that can occupy a specific energy level can be found using the following formula:
Electron Capacity = 2n2
The variable n represents the Principal Quantum Number, the number of the energy level in question.
2nd energy level, the electron arrangement is 2,1 at ground state
The valence electrons of manganese are located in the 4s and 3d energy levels.
The arrangement of electrons in carbon is 1S2 2S2 2P2. Two electrons are in the first energy level, four in the second.1s2 2s2 2p2
Electrons with the smallest amount of energy would occupy the principal quantum energy level of n = 1. This is the lowest energy level, closest to the nucleus of an atom, where electrons are most stable and have the least energy. In this level, there can be a maximum of two electrons, which occupy the 1s orbital.
Valence electrons.
2nd energy level, the electron arrangement is 2,1 at ground state
An atom with seven electrons will have five electrons in the second energy level.
The valence electrons of manganese are located in the 4s and 3d energy levels.
The atomic number of calcium is 20 as it has 20 protons and 20 electrons, they are located outside the Nucleus in the orbits known as energy levels, and are commonly known as shells of the atom. in the first energy level there are 2 electrons, in the second energy level there are 8 electron, in the third energy level there are 8 electrons, and in the fourth energy level there are 2 electrons.
There are 2 electrons in the outer energy level for calcium, as it is located in the 4th (outermost) energy level of the electronic configuration.
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.

Valence electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
