Chapter 2.2 Flashcards
In terms of energy, the relationship between frequency and wavelength is
Frequency is proportional to one over wavelength
In terms of energy, the relationship between frequency and energy is
Frequency is proportional to energy
Emission spectrum
A diffraction grating separating the various wavelengths of light emitted from a gas
Line spectrum
A spectrum that has only certain frequencies/wavelengths of light present
Continuous spectrum
A spectrum that has all frequencies/wavelengths of light present
When do the lines on a line spectrum get closer together?
At higher frequencies/energy
Where does each line in a line spectrum come from?
The transition of an electron from a high energy level to a lower one
When do the different series of lines in a line spectrum occur?
When electrons fall down to different energy levels
Convergence limit
The point when the lines in a line spectrum merge to form a continuum, meaning the electrons can have any energy and are outside of the atom
Aufbau principle
Used to work out the electron configuration of an atom, which is that they fill sub-levels from the lowest energy level upwards, giving the lowest possible energy
Orbital
A region of space in which there is a high probability of finding an electron
What does an orbital represent?
A discrete energy level
What is the max number of electrons an orbital can contain?
Two
Degenerate
Has the same energy
True or false? The orbitals in any subshell are not degenerate
False. All the orbitals in the same subshell are degenerate
