Basic Matter
The scientist who discovered electrons using a cathode ray tube in 1897.
Who is J. J. Thomson?
The chemical species on the right side of a molecular equation
What are the products?
A reaction in solution that forms a solid.
What is a precipitate reaction?
The product of wavelength and frequency.
What is the speed of a wave?
[Kr] 5s24d105p2
What is the electron configuration for Tin (Sn)?
Ernest Rutherford shot alpha particles at this, discovering the atom was mostly empty spaced but contained a positively charge center.
What is gold foil?
What is a mass spectrometer?
What is molarity?
What is constructive interference?
The chemistry and physics name s-, p-, d-, f- orbitals.
What are subshells and angular momentum numbers (L)?
Elements are made up of atoms, atoms of a given element are identical, compounds form when atoms of elements combine, and chemical reactions are the reorganization of atoms.
What is Dalton's Atomic Theory?
The smallest whole number ratio between elements in a compound.
What is the empirical formula?
A reaction in which electrons are transferred between two specie.
What is an oxidation-reduction reaction?
The SI unit associated with a wave's frequency.
What is Hertz (Hz)?
The emission of a set of discrete wavelengths of light for a given element.
What is a line spectrum?
The claim that the same volume of gases, at equal temperature and pressure, has the same number of particles.
What was Avogadro's hypothesis?
Ensuring the law of conservation of mass is followed in a molecular equation through this process.
What is balancing a chemical equation?
The _________ dissolves the _________ in a solution.
What are a solute and solvent?
The ejection of electrons from a metal surface, given a packet of light with sufficient frequency.
What is the photoelectric effect?
The chemistry and physics names for a region of probability for the electron to reside.
What is an orbital or wavefunction (psi)?
The process of separating a mixture by recognizing a difference in particle size between substances.
What is a redox and combustion reaction?
This acid-base reaction process, also called volumetric analysis, can determine the concentration of solution through use of an indicator.
The mathematical relationship between a particle's momentum and its wave-like behavior.
What is the de Broglie wavelength?
This is the name for the effect of electron-electron repulsions inside an atom, electrons in successive shells more "screened" from the nucleus than core electrons.
What is shielding?
