metals
6
What is the energy required to remove an electron called?
electronegative energy
shielding energy
nuclear energy
ionization energy
7
Why does ionization energy decrease going down a group on the periodic table?
increase size of the nucleus
increase number of protons
fewer electrons in the highest occupied energy level
increase in energy levels
8
Why does ionization energy increase going across a period?
increasing shielding
becasue nuclear charge (protons) increases
the nuclear charge (protons) decreases
additional energy levels
