Orbitals

Question 1

orbitals

Answer 1

areas in space around the nucleus in which electrons can be found

they can only exist in specific set of energy levels

Question 2

Electrons transitioning between energy states

Answer 2

electrons can move energy states by absorbing energy to enter a more excited state or emitting energy to return back to the ground state or jump to a lower energy state

electrons always have to return back to the ground state

Question 3

Octet rule exceptions

Answer 3

expanded octet >8 electrons
any element in period 3 and beyond

P (10 e-)
S (12 e-)
Cl (14 e-)

incomplete octet

H, He, Li (2 e-)
Be (4 e-)
B (6 e-)

Question 4

Rule about absorbed energy

Answer 4

an atom or molecule can only absorb energy exactly equal to the different between two energy levels

Question 5

Bohr Model of the Atom

Answer 5

• electrons move around the nucleus in fixed circular orbits
• electrons that orbit further from the nucleus have higher energy
• energy is absorbed when moving from low –> high orbit
• energy is emitted when moving from high –> low orbit

Question 6

Which atoms will show color in a solution?

Answer 6

metals with unfulfilled d orbitals can produce color because it is the only orbital that can split into 2 different energy levels

allows some electrons to jump up to a higher energy level and transmit visible light?
