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

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.

• True

• False

Isotopes of an element have the same number of protons, but different numbers of electrons.

• True

• False

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.

• True

• False

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

• True

• False

% error= (experimental - theoretical)/experimental

• True

• False

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

• True

• False

One mole of an ideal gas = 22.4 Liters at any temperature or pressure

• True

• False

Molar Mass = dRT/P

• True

• False

Real gases behave most like an ideal gas at high temperature and at low pressure. The more polar a gas is and the larger a gas is, the more it will deviate from ideal behavior. Consequently, small, nonpolar gases are the _______ ideal.
