500
Which principle states that the atomic orbitals can hold at most two electrons and they need to have opposite spins?
What is the Pauli exclusion principle.
500
What is the electron configuration for K?
What is 1s22s22p63s23p64s1
500
Which would be the greatest energy emitted? a) n = 4 to n = 1 b) n = 3 to n = 1 c) n = 2 to n = 1 d) they all emit the same energy
What is A
500
Explain how light is emitted.
Electrons absorb energy (from electricity, heat, or light) and they jump to a higher energy level. When they de-excite, they jump back down to a lower energy level and when they do they release that energy in the form of light.
