The number of protons, neutrons and elec...

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

A

104, 71 and 71

B

71, 71 and 104

C

175, 104 and 71

D

71, 104 and 71

Text Solution

Verified by Experts

The correct Answer is:
D
`""_(71)^(175)Lu`
Z = atomic number
Z = No. of Protons = 71 = No. of Electrons
No. of Neutrons = Mass no. - No. of Protons
`=175-71`
`=104`
