Week 2 Flashcards
What is quantum (or wave) mechanics
Provides a mathematical description of the electron that incorporated its wavelike properties
At the heart of quantum mechanics are equations called
Wave functions (or orbitals)
Wave functions is denoted by the greek letter
Psi
Each _____ corresponds to a different energy state for an electron
Wave functions
Each _____ is a sublevel where one or two electrons can reside
Energy state
The ____ associated with the state of an electron and can be calculated from the wave function
Energy
The _____ of finding an electron in a given region of space can be calculated from the wave function
Relative probability
The solution to a wave function can be:___,____,_____
Positive, negative, zero
The _____ of a wave function indicates whether the solution is positive or negative one calculated for given point in space relative to nucleus
Phase sign
Magnitude of crest and troughs
Amplitude
Distance from crest to crest
Wavelength
What is an orbital
is a region of space where the probability of finding an electron is high
What is atomic orbitals
Atomic orbitals are plots of wave function squared in a three dimensions
The subshells are described with the help of
Angular momentum or azimuthal quantum numbers
What is electronic configuration
It is a representation of the arrangement of electrons distributed among orbital shells and subshells
