Chem 11:24:14 Flashcards
Going left to right in a period, atoms become…
Smaller due to increased number of electrons and protons, causes greater nuclear pull towards center.
(Think about each period as a certain energy level, somewhat “restarts” with each new energy level)
Going down a group makes atoms become…
Larger (think electron configuration and how it gets bigger, more energy levels)
-due to internal electron shielding
Going down a group, atoms become
Growing down a period, atoms become
Larger (greater electron config, more energy levels)
Smaller (more protons and neutrons, larger internal pull)
Atomic size:
2 like atoms forced to make a COVALENT BOND, then take the distance between the 2 and cut it in half, than you have the COVALENT RADIUS
The greater the nuclear pull, the more energy needed to…
Remove the first electron (greater ionization energy)
As we go down a group, the ionization energy required…
Goes down (decreases, easier to remove electron)
