why is it the maximum electrons per shell is 2,8,18,32,50 ... Wouldn't 2,8,16,32,50 make more sense mathematically?
Are there any equations the show why this occurs?

71.5 electrons?
Electrons per shell refers to the number of electrons that can occupy a specific energy level within an atom. The first energy level, or shell, can hold a maximum of 2 electrons, while the second and third levels can hold up to 8 electrons each. The number of electrons per shell increases as you move further away from the nucleus.
The electrons in an atom are distributed into different shells according to the Aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels. This means that the first shell is filled before any electrons can occupy the second shell, and so on.
The number of electrons per shell is determined by the atomic number of an element. The atomic number is equal to the number of protons in an atom, which also determines the number of electrons. For example, carbon has an atomic number of 6, so it has 6 electrons, with 2 in the first shell and 4 in the second shell.
The number of electrons per shell can change if the atom undergoes a chemical reaction or gains or loses electrons. This can result in a change in the atom's overall charge and may lead to the formation of ions. However, the number of electrons that can occupy each shell remains the same.
The maximum number of electrons per shell is determined by the formula 2n^2, where n is the number of the shell. For example, the first shell can hold a maximum of 2 electrons (2 x 1^2 = 2), the second shell can hold a maximum of 8 electrons (2 x 2^2 = 8), and the third shell can hold a maximum of 18 electrons (2 x 3^2 = 18). This pattern continues for higher energy levels.
