Unit 2

Question 1

electrons fill the lowest energy level first

Answer 1

Aufbau Principle

Question 2

One electron in each orbital before 2 go in any

Answer 2

Hunds Rule

Question 3

A maximum of 2 electrons may occupy a single orbital

electrons will have opposite spins (one up, one down)

Answer 3

Pauli Exclusion Principle

Question 4

All orbitals of the same type in the same energy level are of equal energy

Answer 4

Aufbau Principle

Question 5

Energy Level

Answer 5

amount of energy an electron needs to exist that certain distance from the nucleus

Question 6

Orbital

Answer 6

Place where electrons are most likely to be found (within energy levels)

Question 7

where do the d orbitals fill? Why?

Answer 7

after the s’s because the have more energy

Question 8

what are photons?

Answer 8

packets of energy (from light, heat, etc)

Question 9

where is the least amount of energy compared to the nucleus ?

Answer 9

least amount is closer to the nucleus because of electrons (opposite charges)

Question 10

why is the most amount of energy farthest away from the nucleus ?

Answer 10

because there is more space for electrons to fill because of the energy levels getting bigger (electrons have opposite charge)
holds most e- -> more space further from the nucleus

Question 11

how many orbitals and electrons in the p block ?

Answer 11

3 p orbitals

6 electrons

Question 12

how many orbitals and electrons in the d block?

Answer 12

5 d orbitals

10 electrons

Question 13

how many orbitals and electrons in the f block ?

Answer 13

7 f orbitals

14 electrons

Question 14

equation to find energy?

Answer 14

E=h*v

Question 15

equation using the speed of light to find a wavelength

Answer 15

C=(wavelength)*v

Question 16

what does v represent ?

Answer 16

frequency

Question 17

unit for energy?

Answer 17

J (Joules)

Question 18

unit for frequency?

Answer 18

1/s

Question 19

speed of light? (C)

Answer 19

3E17 nm/s

Question 20

planks constant (h)?

Answer 20

6.626E-34 JS

Question 21

what happens when electrons jump from level to level

Answer 21

absorbing energy and then releasing energy
(Absorb very specific color light and emit very specific color light)
Every atom has a different energy -> therefore each elements releases different (unique) colors

Question 22

when absorbing, what does an electron do ?

Answer 22

moves from its ground state to a higher energy level (becoming excited)

Question 23

when releasing, what does an electron do ?

Answer 23

electron moves from excited state to a lower state (closer to the ground state) and then eventually returns to the ground state.

Question 24

what does quantum mean?

Answer 24

quantity, specific amount of energy

Question 25

how many energy levels behind is the d orbital ?

Answer 25

1

Question 26

how many energy levels behind is the f orbital ?

Answer 26

2

Question 27

how can electrons move from level to level?

Answer 27

by absorbing and releasing a certain amount of energy

Question 28

certain distance depends on what?

Answer 28

depends on the energy of the electron

Question 29

what shape is the p orbital ?

Answer 29

dumbbell shaped

Question 30

what shape is the s orbital ?

Answer 30

circle, sphere

Question 31

what 2 things produce color?

Answer 31

wavelength and frequency
