AP Chemistry - THOU SHALT NOT FORGET

Front

When an electron is in a higher energy level, it is farther away from the nucleus and has less Coulombic attraction to the nucleus and is therefore easier to remove.

Back

True

Front

When reading a PES graph, the higher the peak, the less electrons there are in that sublevel, and a larger binding energy means that the electrons are closer to the nucleus.

Back

False

Front

Do isotopes of an element have the same number of protons, but different numbers of electrons?

Back

False

Front

Cations (+) are smaller than their atoms since you are removing valence electrons that are farther from the nucleus and anions (−) are larger than their atoms since adding extra electrons increases electron-electron repulsions.

Back

True

Front

The greater the electronegativity difference between 2 atoms, the more polar the bond becomes.

% error = (experimental - theoretical)/experimental

T and V are indirectly related...If you heat a balloon, it will expand.
