Maximum Electron Capacity of Shells in an Atom

1. Break Down the Problem
   The problem requires determining the maximum number of electrons that can occupy the second electron shell of an atom.

2. Relevant Concepts
   The maximum number of electrons $n$ that can occupy a shell in an atom is given by the formula:
   $\text{Maximum electrons} = 2n^2$
   where $n$ is the principal quantum number (the shell number).

3. Analysis and Detail
   For the second electron shell, $n = 2$. Substituting this value into the formula:
   $\text{Maximum electrons} = 2(2^2)$
   This simplifies to:
   $\text{Maximum electrons} = 2 \times 4 = 8$

4. Verify and Summarize
   Therefore, the calculations show that the second electron shell can hold a maximum of 8 electrons. This conclusion aligns with the established rules governing electron configurations in atomic theory.

Final Answer

The maximum number of electrons that the second electron shell in an atom can hold is 8 electrons.
