Recall that valence electrons are the electrons in the outermost shell of an atom and determine an element's chemical properties.
Identify the group number of each element in the periodic table, as the group number often corresponds to the number of valence electrons for main-group elements.
Carbon is in group 14, so it has 4 valence electrons.
Boron is in group 13, so it has 3 valence electrons.
Lithium is in group 1, so it has 1 valence electron, which is fewer than the others.
