3 Electronic Structure & Periodic Properties Flashcards
1
Q
What is a node?
A
Any point of a standing wave with zero amplitude (no motion)
2
Q
What is a ground electron state?
A
The normal basic elements electron configuration
3
Q
What is an excited electronic state?
A
State an atom enters when it receives energy and moves up an orbital
4
Q
What is the Pauli exclusion principle?
A
No 2 electrons in an atom can have the same exact set of Q.N
5
Q
Heisenberg uncertainty principle
A
Fundamental uncertainty that it is impossible to determine simultaneously momentum and position of a particle
6
Q
What is amplitude?
A
Corresponds to the magnitude of waves displacement, higher amplitude =brighter light louder sound
