Question

Each shell surrounding an atom is limited in the number of electrons it can have.

True
False

Answer 1

True. Each electron shell (or energy level) around an atom has a specific capacity for electrons, which is determined by the formula \(2n^2\), where \(n\) is the principal quantum number (the shell level). For example, the first shell (n=1) can hold a maximum of 2 electrons, the second shell (n=2) can hold up to 8 electrons, the third shell (n=3) can hold up to 18 electrons, and so on.
