Chemistry electron question?

Question

1. The frequency and wavelength of all waves are:
a. directly related
b. inversely related
c. unrelated
d. equal

2. The SI unit of cycles per second is called a :
a. photon
b. quantum
c. hertz
d. hund

3. Among the following groups of atoms, which have the same outer energy level configurations?
a. H,He
b. Li,Be,N,Ne
c. Mg,Al,Ca,Ga
d. N.P,As,Bi

4. The wavelength of light with a frequency of 2.50 x 10^13 x s^-1 is:
a. 1.20 x 10^5 m
b. 8.33 x 10^5 m
c. 1.20 x 10^-5 m
d. 8.33 x 10^-5 m

5. Once the electron in a hydrogen atom absorbs energy, it:
a. is now in its gound state
b. is now in its excited state
c. has released a photon
d. none of these

Answer 1

1. b
Because
'1/s' is inversly related to 's'

2. c
Because
1/s AKA Hertz

3. d
Because
N.P,As,Bi are all in the same chemical group

4. b
Because
(3*10^8)m/s / (2.50 * 10^13)Hz = 1.20 x 10^-5 m

5. b
