I dont have a pen! Sodium, do you mind giving me one
of course, chlorine I've got an extra one so you can keep it
in ionic bonding, electrons are transferred completely between atoms. in this case, the pencils are "valence electrons", and the sttudents are the two atoms (sodium and chloride) . valence electrons are significant to every bond because they are the one that allow for any bond to happen. as demonstrated , during an ionic bond, one of the atoms (in this case chlorine) gets to "keep" the valence electron/pen
OH NO! we both forgot our textbooks! can we Share yours carbon?
of course oxy and gen
in covalent bonding, the electrons are shared between atoms, and they are never removed all the way. in this example, the valence electrons shared are represented by the textbook, which is shared among the atoms. in this case the atoms sharing the electrons consist of three atoms- two oxygen and one carbon
