The number of protons, neutrons and electrons in 175_71 Lu , respectively, are:

A

71, 104 and 71

B

104, 71 and 71

C

71, 71 and 104

D

175, 104 and 71

Text Solution

Verified by Experts

The correct Answer is:
A
`""_(71)^(175)Lu`
Number of protons = 71 = Number of Electrons
No. of Neutrons = Mass number - Number of Protons
= 175 - 71
= 104.
