Electronic Structure.

Question 1

What is Planck’s constant?

Answer 1

6.626 x 10^-34 J*S

Question 2

What is the Speed of light?

Answer 2

3.00 x 10⁸M*S

M= Meters

Question 3

What equation to use to find the energy/ Wave length of a Photon?

Answer 3

E= hc/λ

Question 4

h?

Answer 4

Planck’s Constant

Question 5

c?

Answer 5

Speed of light.

Question 6

What are the units of E= hc/λ

Answer 6

M/S/J

Meters/ Seconds /Joules

Question 7

What does S^-1 mean?

Answer 7

Per second, the negative exponent is meant to represent “per” and can be squared or cubed in some cases. in Frequency this is used to show the number of waves passed per second.

Question 8

Equation for Energy/ Frequency of a Photon?

Answer 8

E=hv

Question 9

What is v?

Answer 9

v is the Frequency

Question 10

What are the units of E=hv

Answer 10

J/S/ (Hz or S^-1)

Question 11

What electronic Transitions emit the most energy?

Answer 11

Transitions from the highest to lowest levels will emit the most energy, so N2 to N1 will emit more energy than N4 to N3

Question 12

What is a Quantum number?

Answer 12

A unique number of a specific electrom within an atom.

Question 13

What are the quantum orders?

Answer 13

N, ℓ, Mℓ, & Ms

Question 14

What is Quantum n?

Answer 14

The level the electron is in, can be 1-8
EX: an electron represented by 4s³ n=4

Question 15

What is Quantum ℓ?

Answer 15

The quantum sublevel # and represents the shape of the sublevel. This number is from the SPDF of the ground state electron configuration. S=0, P=1, D=2, F=3.

Question 16

What is Quantum mℓ?

Answer 16

This number represent where in space the electron is at, this is from the sublevel the electron at and which space/ orbital the electron is in can be from -3-+3. EX: an e- at sublevel D in the middle will be mℓ=0, at the far left mℓ=-2, far right mℓ=+2

Question 17

What is Quantum ms?

Answer 17

Ms is the Spin of the electron, this can be +1/2 or -1/2. an up arrow is (+) and down arrow is (-)

Question 18

What are the orders of the sublevels?

Answer 18

SPDF

Question 19

How many electrons can each sublevel hold?

Answer 19

S=2, P=6, D=10, F=14

Question 20

how many rows of with F are possible in ground state electron configuration?

Answer 20

2 rows.

Question 21

At what principle level does D start?

Answer 21

Level 3

Question 22

How many electrons are in each orbital?

Answer 22

2
