How many valence electrons are in an atom of sulfur?

Neutral sulfur has 16 electrons because its atomic number is 16. Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and six electrons in the 2p orbitals. read more

Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and six electrons in the 2p orbitals. These electrons are part of the first and second energy levels, the electron core. The next energy level, the last one, is the outermost energy which comprises the valence shell. read more

Sulfur has six valence electrons, meaning that each atom of this element has six electrons in its outermost shell. The number of valence electrons that each element has can be predicted based on its location on the periodic table, though this only applies to neutral atoms. read more

The number of valence electrons are equal to the number of electrons in the outermost shell of the atom. The atomic number of sulphur is 16, and therefore the sulphur atom has 16 electrons in its orbits. The first shell can have a maximum of 2 electrons, and the second shell a maximum of 8 electrons. read more
