|
|
Term
What do psi and psi squared represent in the Quantum Mechanical Model of the atom |
|
Definition
psi= solution to wave equation (orbitals) psi squared= probability of finding an electron |
|
|
Term
How does the probability of finding an electron in a 1s orbital vary with distance from the nucleus. Compare this to the 2s orbital |
|
Definition
Probability decreases as the distance from the nucleus increases. 2s orbital is larger with node |

|
Term
Is light a wave or a particle? Explain |
|
Definition
It's both. It will behave like a particle in some instances, and like a wave in others. This phenomenon is called particle-wave duality. |
|
|
Term
Is an electron a wave or a particle? Explain |
|
Definition
Electrons display properties of both. |
|
|
Term
Why is impossible to measure the position and velocity with infinite accuracy at the same time? |
|
Definition
In quantum mechanics, the Heisenberg uncertainty principle states a fundamental limit on the accuracy with which certain pairs of physical properties of a particle, such as position and momentum, can be simultaneously known. In other words, the more precisely one property is measured, the less precisely the other can be controlled, determined, or known. |

|
Term
Describe Planck's original hypothesis and what Einstein did |
|
Definition
He viewed his strange assumptions as mathematical constructions to provide a formula that fit the experimental data. It was not until later, when Einstein used very similar ideas to explain the Photoelectric Effect in 1905, that it was realized that these assumptions described "real Physics" and were much more than mathematical constructions to provide the right formula. |
