Which of the following is the WORST explanation for the increase in ionization energy of the elements going from left to right across a row of the periodic table?


Nonmetals tend to attract electrons more in chemical bonds.


The nuclei are closer to the electrons shared between the atoms in the chemical bond.


The atoms are smaller as one goes across a row due to the increased number of protons in the nucleus with the electrons still at relatively the same distance away.


Metals and the elements further to the left side of the periodic table are more likely to give up electrons in bonding than to acquire new ones.
