Answer 1-4 (#3 and #4 are tables)
shell provides stability to the atom. Different chemical bonds are based on the way in which the atoms fill their valence shells. The major types of chemical bonds include: ionic bonds covalent bonds (both types, i.c. polar covalent and non-polar covalent bonds), and hydrogen bonds. Atoms can use two strategies to fill their valence shell: they can share electrons between their valence shells, or they can give or take electrons from other nearby...
