In a calcium (Ca) atom in the ground state, the electronic configuration is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².
The electrons that possess the least amount of energy are located in the innermost electron shell, which is the first electron shell (1s²).
Therefore, the correct answer is (1) first electron shell.
