Ideal Gases
This constant (R) in the ideal gas law has a value of 8.314 J/(mol·K)
Unlike ideal gases, real gas particles have this, which becomes significant at high pressure.
What is Volume?
These are atoms of the same element with different numbers of neutrons.
This trend describes the energy required to remove an electron from a gaseous atom.
What is Ionisation Energy?
This term describes the distance between two consecutive peaks of a wave.
What is a Wavelength?
According to this law, at constant temperature, the pressure of a gas is inversely proportional to its volume.
What is Boyle's Law?
Real gases deviate most from ideal behavior under these two physical conditions.
What is High Pressure and Low Temperature?
This principle states it is impossible to know both the position and momentum of a particle simultaneously.
What is the Heisenberg Uncertainty Principle?
Moving left to right across a period, atomic radius generally does this.
What Decreases?
The type of spectrum produced when an atom's excited electrons drop back down to lower energy levels.
What is an emission spectrum?
This is the volume occupied by one mole of an ideal gas at STP (0°C and 100 kPa).
What is 22.7 L?
Why is the measured pressure of a real gas usually lower than the pressure predicted by the Ideal Gas Law?
What are Attractions (particles pull back on each other instead of hitting the wall)?
The type of electron transition that occurs when an atom absorbs energy and an electron moves to a higher shell.
What is excitation?
This property measures an atom's ability to attract shared electrons in a chemical bond.
What is Electronegativity?
This principle states that all matter exhibits both wave-like and particle-like properties.
What is Wave-Particle Duality (or de Broglie Hypothesis)?
This law states that the total pressure of a mixture of gases is the sum of their individual partial pressures.
What is Dalton's Law?
This specific physical change occurs to a real gas when the attractive forces finally "win" over the kinetic energy of the particles.
What is Liquefaction (or Condensation)?
This principle explains why two electrons in the same orbital must have opposite spins (+1/2 and -1/2).
What i the Pauli Exclusion Principle?
This is the specific energy change when an electron is added to a neutral gaseous atom.
What is Electron Affinity?
This equation relates the energy of a photon to its frequency.
What is Planck's Equation (E = hv)?
At a given temperature, all gas particles in a sample have the same average value of this.
What is Kinetic Energy?
This group of elements on the periodic table that act most like an Ideal Gas because they are small and non-polar.
What are Noble Gases?
This rule states that electrons fill degenerate orbitals singly before pairing up.
What is Hund's Rule?
This effect occurs when inner electrons block the nuclear charge from outer electrons.
What is Shielding (or effective nuclear charge)?
When light shines on a metal and ejects electrons, it is known as this effect.
What is the Photoelectric Effect?
