|
How is the ATOMIC RADIUS arranged on the periodic table? Why?
|
Increase down a group becuase adds energy levels
Decreases across a period because nuclear charge(more Protons) without additional energy levels pulls electrons in closer. |
|
|
How are the Ionization Energy arranged on the periodic table?
|
Increase Across a period because valence electrons experience a greater nuclear force(they are in lower energy levels) Smaller atoms have a higher ionization energy
Decreases down a group because valence electrons removed are farther from the nucleus because they are in higher energy levels. Bigger atoms have lower ionization energy |

How are the eletronegravitity arranged on the periodic table? Why?
|
increases across periods because smaller atoms have greater nuclear charge and thus, more force to attract electrons.
Decreases down a group because atomic size increases and valence electrons are farther from the nucleus. |
