2.6 Bohr + Quantum Theory

Question 1

Define ‘orbital’

Answer 1

– region of space around the nucleus of an atom that has a 90% chance of containing an electron
– depends on amount of energy

Question 2

The modern quantum mechanic approach treats the electrons as…

Answer 2

waves w/ specific amounts of energy depending on the region of space they are in.

Question 3

Describe the principal energy levels

Answer 3

start from loweswt (n = 1) and increases up to 7. Corresponds to row # in the periodic table

Question 4

What are the sublevels? (quantum number)

Answer 4

– each energy level is divided into 1+ sublevels where the # of sublevels are the same as the quantum # within that energy level.
– corresponds to a particular shape

Question 5

Describe the “s” sublevel (# of orbital and max electrons)

Answer 5

– 1
– 2

Question 6

Describe the “p” sublevel (# of orbital and max electrons)

Answer 6

– 3
– 6

Question 7

Describe the “d” sublevel (# of orbitals and max electrons)

Answer 7

– 5
– 10

Question 8

Describe the “f” sublevel (# of orbitals and max electrons)

Answer 8

– 7
– 14
