Answer:
(n, l, m sub l, m sub s)
N: principle quantum number (1,2,3,4,etc)
l: angular momentum quantum number, the shape (l has to be at least 1 less than n, but can be 0 depending on n)
M sub l: magnetic quantum number (l determines this number)
M sub s: spin quantum number (can only ever be 1/2 or -1/2)
Explanation:
- Light energy from sun is converted into electrical energy in a solar cell.
- Electrical energy is stored as chemical energy in the solar cell.
- Chemical energy is converted back into electrical energy at night.
- Electrical energy is converted into light energy from the street lamp.
1st energy level can hold 2 electrons
2nd energy level can hold 8 electrons
3rd energy level can hold 8 or 18 electrons
