b. frequency of

c. probability of finding

d. wavelength of

2. The greater the principle quantum number of an electron in a hydrogen atom, the greater the ___________ of the atom.

a. potential energy

b. wavelength

c. speed

d. frequency

3.The principle quantum number for an electron about an atom is designated by ___________

a. a positive or negative spin

b. the letters s, p, d, f

c. an integer value from 0 to infinity

d. an integer value from 1 to infinity

Answer 1

1. Atomic orbitals are a mathematical representation of the probability of finding an electron in the region around the nucleus of an atom.

Therefore option c is correct

2. The greater the principle quantum number of an electron in a hydrogen atom, the greater the potential energy of the atom.

Therefore option a is correct.

3.The principle quantum number for an electron about an atom is designated by

an integer value from 1 to infinity and is designated by n

Therefore option d is correct.
