1.) A covalent bond is a when two or more valence electrons are shared between two atoms.

3.) This analogy describes the way that shared electrons hold together atoms in a covalent bond because the dogs represent the atoms and the sock represents an electron and they are sharing it by both tugging on it. 

4.) Each dot in a Lewis dot structure represents a single valence electron.

5.) The advantage of using a dash (structural formula) instead of using electron dots to represent a covalent bond is that the dash is easier to write. Dashes also clearly show which atoms are sharing which electrons. 

21.)
