Chapter 3 Day 1/2

Question 1

What is electromagnetic radiation and how does it travel?

Answer 1

Light, travels in an oscillating field

Question 2

Significance, symbol, and units of Wavelength?

Answer 2

Determines color
λ
distance units

Question 3

Significance, symbol, and units of Frequency?

Answer 3

How many peaks pass a fixed point in 1 second
V
1/sec or Hz

Question 4

Symbol and value of the speed of light?

Answer 4

C

3.00 x10^8 m/sec

Question 5

Relationship of Frequency, Wavelength, and Speed of Light?

Answer 5

V= C/λ

Question 6

What is a photon, how does it travel, and how to calculate its NRG?

Answer 6

A particle with NRG and no mass
Travels in waves
E=hV where “h” is a constant

Question 7

Idea of continious spectrum?

Answer 7

White light is a combination of all colors

Question 8

What is a line spectrum/ significance?

Answer 8

A spark is added to an elemental gas, and the colors it emits at certain wavelengths determines the “identity” of the element (like a fingerprint)

Question 9

What does the Rydberg Equation do?

Answer 9

Calculates λ using orbital positional numbers from the Line Spectrum

Question 10

What is Bohr’s Model?

Answer 10

Electrons orbit the nucleus

Question 11

What is the Quantum Model?

Answer 11

The energy of electrons is Quantized, therefore different orbital numbers

Question 12

What is an orbital, how are levels distinguished, and what is the significance of that?

Answer 12

an electron cloud
where “n” is the orbital number
and “n” is The Principal Quantum #

Question 13

Relation of NRG in orbitals and distance from nucleus?

Answer 13

NRG Increases as Distance Increases

Question 14

What does Bohr/s equation do?

Answer 14

Calculates NRG (in J/s) of an orbital (n)

Question 15

How do electrons behave?

Answer 15

They behave as waves
