Is my Chemistry answer correct? :) I feel confident in my answer...but i'd like reassurance!!! :))) Which of the following atoms has six valence electrons? (2 points) Answer carbon (C) cesium (Cs) chromium (Cr) sulfur (S) My answer is sulfur

OpenStudy (anonymous):

Sulphur is on group 6 of the periodic table and its electron structure gives it 6 electrons in the outer shell, hence, 6 valence electrons.
