Ch3 Arrangement of Electrons in the Atom Flashcards
1
Q
Energy level
A
The fixed energy value that an electron in an atom may have
1
Q
Ground state of an atom
A
The electrons occupy the lowest available energy levels
2
Q
Excited state of an atom
A
The electrons occupy higher energy levels than those available in the ground state
3
Q
E2 - E1 = hf
A
E1- Energy of higher energy level
E2- Energy of lower energy level
h- Planck’s constant
f- Frequency of light emitted
4
Q
Heisenberg’s Uncertainty Principle
A
States that it is impossible to measure at the same time both the velocity and the position of an electron
5
Q
Orbital
A
A region in space within which there is a high probability of finding an electron
6
Q
Sublevel
A
A subdivision of a main energy level and consists of one or more orbitals of the same energy
