How do you know if electrons are non-bonding?
How do you know if electrons are non-bonding? Because it takes two electrons to form a covalent bond, we can calculate the number of nonbonding electrons in the molecule by subtracting two electrons from the total number of valence electrons for each bond in the skeleton structure. How many non-bonding electrons are there? The number […]

Why do plant cells have cell walls and animal cells do not?
