| When reading a PES graph, a larger binding energy means that the electrons are (closer to/farther from) the nucleus? | closer to |
| When an electron is in a higher energy level, it is _______ from the nucleus and therefore has less Coulombic attraction to the nucleus and is, therefore, easier to remove (i.e. it has a lower 1st ionization energy.) | farther |
| When an electron is in a higher energy level, it is farther from the nucleus and therefore has ____ Coulombic attraction to the nucleus and is, therefore, easier to remove (i.e. it has a lower 1st ionization energy.) | less |
| When an electron is in a higher energy level, it is farther from the nucleus and therefore has less Coulombic attraction to the nucleus and is, therefore, ______ to remove (i.e. it has a lower 1st ionization energy.) | easier |
| When an electron is in a higher energy level, it is farther from the nucleus and therefore has less Coulombic attraction to the nucleus and is, therefore, easier to remove (i.e. it has a _______ 1st ionization energy.) | lower |
| Moving across a row on the periodic table, the Zeff _____ therefore the valence electrons are more attracted to the nucleus, therefore the atomic radius decreases and, the ionization energy increases. | increases |
