(giving 300 points based off of 3 posts to the most answer)
set 1:
neon (ne)
helium (he)
set 2:
lithium (li) and fluorine (f)
magnesium (mg) and oxygen (o)
set 3:
2 fluorine (f) atoms
chlorine (cl) and hydrogen (h)
will the atoms in set 1 form any bonds with each other? why or why not?
what type(s) of bonds will be formed by the pairs in set 2? why?
move the push pins and model the bonds that would form by the atoms in set 2. what do you notice about the atoms now? in your response, state the charge (+ or -) of each atom and explain how the charges affect the bond.
what type(s) of bonds will be formed by the pairs in set 3? why?
move the push pins and model the bonds that would form by the atoms in set 3. what do you notice about the atoms now? in your response, state the charge (+ or -) of each atom and explain how the charges affect the bond.
drawing on what you observed in this lesson, compare and contrast ionic bonds, covalent bonds, and atoms with full octets.
