The first energy level is the 1s orbital, which can hold two electrons. Hydrogen is the first element, with just one electron, you write this down as 1s1. Helium is the second element, with two electrons, you write this down as 1s2. The second energy level has an s orbital and three p orbitals, holding two electrons each, making a total of eight. This element would be neon, you would write its electron configuration as 1s22s22p6. S orbitals are spherical; p orbitals are figure of eight shaped, with three arranged at right angles to one another. Each takes two 'spin-paired' electrons - one 'spinning up' and the other 'spinning down'. [apologies to previous contributor; I accidentally deleted your answer ]
For hydrogen (atomic number 1), there is 1 electron in the first energy level. For helium (atomic number 2), there are 2 electrons in the first energy level. For lithium (atomic number 3), there are 2 electrons in the first energy level and 1 electron in the second energy level. For beryllium (atomic number 4), there are 2 electrons in the first energy level and 2 electrons in the second energy level. For boron (atomic number 5), there are 2 electrons in the first energy level and 3 electrons in the second energy level.
The maximum number of electrons that can be found in the first energy level (or inner level) of an element is 2 electrons. This is because the first energy level only has one subshell, which can accommodate a maximum of 2 electrons.
carbon has 2 electrons in its first energy level and 4 in its secound energy level because carbons atomic number is 6. 4+2=6.
The number of electrons in each energy level is determined by the formula 2n², where "n" is the principal quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
The maximum number of electrons in each energy level is determined by the formula 2n^2, where n represents the energy level (shell). For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.

All elements except hydrogen have two electrons in the first energy level.

2 electrons
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
The number of electrons in each energy level is determined by the formula 2n², where "n" is the principal quantum number of the energy level. For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.

The maximum number of electrons that can be held in an energy level is given by the 2n^2 rule, where n is the principal quantum number of the energy level. So, for example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
There are 8 electrons in the second energy level of magnesium. This can be determined because magnesium has an atomic number of 12, meaning it has 12 electrons in total. The first energy level is filled with 2 electrons, leaving 10 electrons to distribute in the remaining energy levels, with 8 of those in the second level.
Phosphorus has 5 electrons in its outermost principal energy level.
