How is the formation of covalent bonds similar to kids sharing markers? how is it different? if possible, discuss your answer with your classmates and teacher?

A covalent bond means shared electrons between atoms. This is similar to kids sharing markers because the markers (electrons) are being shared between the kids (atoms). Covalent bonds are different than this metaphor because 1) the electrons are constantly moving about while the kids can steal and keep the markers and 2) the electrons and atoms are physically smaller
