In a polar covalent bond, how do you determine which is positive and which is negative?
Find number of protons in each element and the larger atomic number will have the + because it has more protons to attract the electrons.

400
This causes an atom to be more or less reactive? a. number of valence electrons b. ionization energy c. atomic radius d. none of the above e. all of the above
e. all of the above # of electrons determine how many it needs to gain or lose to have 8 valence electrons. (octect rule) ionization energy- energy needed to remove electrons. decreases as you go down period, increases as you move across atomic radius-how close the electrons are to nuclues, larger as you go down, smaller as you go across
