| Question | Answer |
|---|---|
| What happens to ionization energy as you move down the groups? | it decreases |
| What happens to atomic radii as you move down the groups? | it increases |
| What happens to metallic character as you move down the group? | it increases |
| What happens to electronegativity as you move down the group | it decreases |
| What happens to ionization energy as you move across the periods? | it increases |
| What happens to atomic radii as you move across the periods? | it decreases |
| What happens to metallic character as you move across the periods? | it decreases |
| What happens to electronegativity as you move across the periods? | it increases |
| Why does atomic radii move in that way down a group? | as you move down, more energy levels are added and the more atoms in the center, the more attracted the electrons will become |
| Why does metallic character move in that way down a group? | as atomic radii increases the electrons become farther apart from the protons making them easier to lose |
| Why does ionization energy move in that way down a group? | as radii increases the valence electron and nucleus attraction lessens and less energy is needed |
| Why does electronegativity move in that way down a group? | as radii increases it is harder for protons in the nucleus to attract electrons in other atoms |
| Why does atomic radii move in that way across a period? | electrons are pulled closer together (because an atom is mostly empty space) due to each new successive element added |
| Why does metallic character move in that way across a period? | as radii decreases, it becomes harder to lose electrons |
| Why does ionization energy move in that way across a period? | as radii decreases , the attraction between valence electrons and the nucleus is strengthened and more energy is needed |
| Why does electronegativity move in that way across a period? | as radii decreases, it becomes easier for protons in the nucleus to attract electrons of other atoms |
