1
Q

Electron absorbtion moves from lower energy to higher level or higher energy level to lower.

A

Lower to higher.

2
Q

The higher the wavelength what happens to the level of energy?

A

The lower the energy. E=hc / lambda

3
Q

How do you calculate wavelength if mass and velocity are given?

A

Lambda = h / mv, where m is mass in kg, v is velocity, h is planck’s constant.

4
Q

What orbital do you have when l = 0

A

S orbital and as l goes up, the orbital goes up. e.g. 1 = p, 2 = d, 3 = f, 4 = 5.

5
Q

If n = 4 what can l equal?

A

l can equal an integer -1 which would be 3, 2, 1, 0.

6
Q

If l = 3 what can ml =?

A

2, 1, 0, -1, -2

7
Q

True or false. An atom can have a configuration above it’s place in the periodic table.

A

False.

8
Q

How do you calculate formal charge?

A

Valence electrons minus electrons in structure.

9
Q

If you have two lewis structures with the same formal charge how do you determine which one is more stable?

A

You choose the structure that has the more negative charge on the more electronegative atom.

10
Q

0 charges of atoms are included or not included in the formal charge of the molecule.

A

Not included.

11
Q

How do you calculate bond order?

A

Number of bonds / Number of Bond Groups

12
Q

Energy of light equation is what?

A

=hv=hc/lambda, h equals plancks constant, v equal frequency.

13
Q

Wavelength of a photon equation equals..

A

hc/absolute value of change in energy

14
Q

Energy of a photon =

A

= hc/lambda

15
Q

Energy =

A

hv

16
Q

c =

A

lambda f

17
Q

E =

A

hf

18
Q

Energy of light =

A

hc/lamba

19
Q

Wavelength =

A

= h/p p equals momentum

20
Q

Wavelength =

A

h/mu m = mass in kg, u = velocity.

21
Q

v=

A

h/mlambda mass in kg
