Question: how many total valence electrons are there in a molecule of glucose (c6h12o6)?
Answer: Stefan V. The number of valence electrons for molecules can be calculated by adding the valence electrons of all the atoms that form that respective molecule. 2⋅1+1⋅6=8 valence electroncs. 2⋅1+1⋅6+4⋅6=32e− .
