Answer:
3rd subshell
6 electrons
Step-by-step explanation:
Each element on the periodic table has a unique number of electrons when in a neutral state.
Highest-Energy Subshell
The highest energy subshell in an atom is known as the valence shell. We can use the periodic table to find what level the valence shell is at. The valence shell of an atom depends on the row on the periodic table. Sulfur (s) is in the 3rd row of the periodic table. This means that its valence shell is the 3rd subshell. So, its highest-energy electrons are in the 3rd subshell.
Valence Electrons
The electrons in the valence shell are called valence electrons. The number of valence electrons in an atom depends on its column on the periodic table. For main group elements, the number of valence electrons is equal to the last digit of the column number. For example, sulfur is in the 16th column, so it has 6 valence electrons. This means that there are 6 electrons in the highest-energy subshell.
