This principle states that electrons must fill lowest energy shells first
What is the Aufbau principle
This person wrote a paper on the photoelectric effect and merely changed the world.
Who is Einstein?
Ammonia has this molecular shape
Neutral forms of this column are explosive when they meet water
What is the first column (alkali metals)?
This is an energy changed solely associated with a temperature difference
What is heat?
This principle states that no two electrons in an atom can have all four quantum numbers be identical
What is the Pauli exclusion principle?
This person is credited with the discovery and identification of the electron
Who is Sir JJ Thomson?
Water has this electronic geometry
What is tetrahedral?
A change of matter from Vapor to liquid
What is Condensation?
This is an energy changed associated with movement or physical exertion, but not a temperature change
What is work?
The quantum mechanics treats atoms not just like particles, but also like this
What are waves?
This person discovered quantified the number of atoms or molecules per one mole of a substance
Who is Avogadro?
Oxygen in ethanol has this geometry
What is tetrahedral?
This force, resulting from transient dipoles in the electron cloud, is the weakest intermolecular force?
(London) dispersion forces?
This type of reaction releases energy?
What is exothermic?
Electromagnetic radiation containing a discreet amount of energy
This Danish physicist helped to develop the quantum model by (incorrectly) defining electron orbitals to be strictly circular and step-wise, like 'rungs on a ladder'
Who is Niels Bohr?
PCl5 has this molecular geometry
What is trigonal bipyrmidal?
A multitude of compounds that share the same molecular formula, but have different arrangements
What is an isomer?
This law states that energy cannot be created or destroyed
What is the first law of thermodynamics?
This is the distance between peaks or valleys in a quantum mechanical description
What is the wavelength?
This person discovered that atoms have small dense nuclei, using gold foil.
Who is Rutherford?
trigonal pyrimidal
A change from a solid to a gas
What is Sublimation?
This type of energy transfer is associated with breaking a chemical bond
What is endothermic?
