1.1 - 1.4

Question 1

What is inversely proportional to the energy of a photon?

Answer 1

The wavelength of the emitted photon, as the wavelength decreases when energy increases

Question 2

Why do certain colors get emitted by certain elements

Answer 2

Certain colors are emitted because the energy (light or electricity or heat) coming in will excite the electrons and make em release photons

Question 3

What is the emitted photon from level 5 to 2 called?

Answer 3

It is part of the Balmer series, and will emit blue light.

Question 4

What is the Lyman Series?

Answer 4

It’s any UV light as a result of any energy level dropping down to 1

Question 5

What is the Paschen Series

Answer 5

Infrared light emissions, anything to level 3.

Question 6

What is Ground State?

Answer 6

Ground state is level 1, the lowest possible energy level for an electron.

Question 7

What is a spectral reading for a compound and how can we tell what is in the compound

Answer 7

A spectral reading for an element tells us which wavelengths are emitted, we can then compare it to the spectral emissions of certain elements to see if they are present in the compound

Question 8

How many electron pairs does an f-type orbital have?

Answer 8

It has 7 pairs of electrons.

Question 9

What is the shape of each type of orbital?

Answer 9

S is a circle, p is a hourglass, d is a four leaf clover or bowtie, f we dont need to know.

Question 10

What kinds of orbitals can be in the 6th energy level

Answer 10

There can either be 6s, 6p or 6d

Question 11

Which type of electrons are filled first? (Hint: up or down)

Answer 11

Up-spinned electrons are always filled first.

Question 12

What is the aufbau principle? (Hint; aufbau pyramid / diagram)

Answer 12

Certain orbitals will be filled in a specific order, so 4s will be filled before 3d.

Question 13

What is the closest shorthand to Cl

Answer 13

The closest shorthand would be Neon.

Question 14

What is the exception to the aufbau principle?

Answer 14

The exception to the aufbau principle is when an ion will pull electrons out of 4s before 3d to either be full or half-full.

Question 15

What is a principal quantum number (also known as n)

Answer 15

The principal quantum number is basically the energy level (2 in 2, 3 in 3p etc)

Question 16

What is an azimuthal quantum number (l) or secondary quantum number

Answer 16

An azimuthal quantum number is the type of orbital (s, p, d, or f) if allowed, depending on n’s value.

Question 17

What is a magnetic quantum number (ml)

Answer 17

A magnetic quantum number represents a specific electron pair within the orbital, it will be from range -L to L.

Question 18

What are the acceptable values for spin quantum number

Answer 18

+ or - 1/2

Question 19

What are the two ideas of periodic trends?

Answer 19

1) as the number of protons increases, the pull on the electrons increases
2) as the number of shells increases, the pull on electrons gets weaker because the electrons get farther.

Question 20

What is atomic radius?

Answer 20

Atomic radius is the radius of the nucleus to the outermost electron

Question 21

What is the trend for atomic radius?

Answer 21

Going down, it increases
Going right, it decreases

Any variant of this answer is ok

Question 22

What is ionization energy

Answer 22

Ionization energy is the energy required to rip away a single electron from an atom.

Question 23

What is the trend for ionization energy

Answer 23

Ionization energy increases going to the right
It decreases going down.

It’s because there are more protons going right, so it’s harder to rip apart.

Question 24

What is the exception for ionization energy

Answer 24

Stable subshells will be harder to rip an electron from than an unstable subshell.

Question 25

What is electronegativity

Answer 25

Electronegativity is how much an atom would like to pull an electron in

Question 26

What is the trend of electronegativity

Answer 26

It decreases going down and increases going right

Question 27

What is electron affinity

Answer 27

Electron affinity is how much energy is freed when an atom gets a single electron.
It will party hard when it becomes stable

Question 28

What is the exception for electron affinity

Answer 28

Electron affinity will be lower for atoms with half or full sub shells / orbitals (prior to getting that new electron)
