Identify the group number of the chalcogens in the periodic table. Chalcogens are elements in Group 16.
Recall that the group number for main-group elements corresponds to the number of valence electrons for those elements.
Since chalcogens are in Group 16, they have 6 valence electrons.
Understand that valence electrons are the electrons in the outermost shell of an atom and determine chemical properties and bonding behavior.
Therefore, the number of valence electrons for chalcogens is 6.
