Which of the following statements is true?

Question

Quizplus · Accepted Answer

The outermost occupied electron shell of an atomic is called the valence shell. The electrons in the valence shell determine the chemical properties of that atom (and element). Electrons in the valence shell are known as valence electrons.
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
You may use the diagram of the Bohr Model below as a visual reference for the breakdown of electron numbers based on the shell.
