Electron Configuration

Question 1

What does Heisenberg’s Uncertainty Principle explain?

Answer 1

That we can never know exactly where an electron is at a given moment but we can calculate the probability of the area in space where it possibly is. Those areas in space are called orbitals.

Question 2

An s orbital has space for ___ electrons while the p orbital for _____ (2 in p(), 2 in p() and 2 in p())

Answer 2

2
6
X,Y,Z

Question 3

Upon inspection of the energy jumps when analyzing ionization energies we conclude that some energy levels contain _________.

Answer 3

Sub-levels

Question 4

What must we do when we indicate electron distribution?(3)

Answer 4

• No more than two electrons can occupy one orbital and when they do, they must spin in different directions.
• Electrons will occupy the orbital which has the lowest possible energy.
• Electron will occupy an orbital alone rather than share it.
