1
Q
What is an energy level(1)
A
-the fixed energy value that an electron in an may have
2
Q
What is the ground state (1)
A
-when the electrons of an atom occupy the lowest available energy level
3
Q

Q
What does Heisenberg’s Uncertainty Principle state(1)
A
-it states that it is impossible to measure at the same time both the velocity and the position of an electron
6
