Lecture 3 Flashcards
1
Q
How many electrons can the first shell hold?
A
2 electrons
2
Q
How many electrons can the 2nd,3rd, and 4th shell hold?
A
8 electrons
3
Q
Do electrons have potential energy?
A
yes
4
Q
Where are electrons found?
A
In the outer shell of the atom.
5
Q
when do electrons move from one shell to another?
A
They can only move if the energy that the electron gains or loses is precisely equal to the difference between the energy levels of the two shells.
6
Q
Why do electrons have potential energy?
A
Because of their distance from the nucleus.
6
Q
What is potential energy?
A
It’s the energy that matter contains.
7
Q
When does the energy level increase in a shell?
A
When the distance from the nucleus Increases.
