electron configs
Not using the short cut what is the electron configuration for C?
1s2 2s2 2p2
Si unit for cycles per second
hertz
True/False
The fixed energies an electron can have is called Energy Levels
True
True/False
metals emit electrons under certain colors because of the greenhouse effect
False
photoelectric effect
Not using the shortcut what is the electron configuration for K?
1s2 2s2 2p6 3s2 3p6 4s1
photon
what is the term for describing the probability of finding an electron in various locations around the nucleus?
atomic orbital
What is planks constant? (number and label!)
6.626 x 10-34 J * s
Using the shortcut, what is the electron configuration for I?
[Kr] 5s2 4d10 5p5
what is it called when an electron has its lowest possible energy?
ground state
True/False
The wavelength required to change energy level is frequency
False
it is the number of wave cycles to pass a given point per unit of time.
states it is impossible to know both velocity + position of a particle at the same time.
using the shortcut, what is the electron configuration for Pr?
[Xe] 6s2 4f3
what is the amount of energy required to move an electron to from one energy level to another energy level.
quantum
name the principle that states an atomic orbital may describe at most two electrons.
Pauli Exclusion Principle
why do fireworks emit light?
goes from excited state ---> ground state.
using the shortcut, what is the electron configuration for Os?
[Xe] 6s2 4f14 5d6
what is the principle for electrons occupying the orbitals of lowest energy first?
aufbau principle
what is Hund's Rule
Electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible.(they don't want to spin the same way within an orbital)
Describe classical mechanics vs. quantum mechanics.
classical mechanics- motions of bodies much larger than atoms
quantum mechanics- motions of subatomic particles +atoms as waves
