A positron is emitted from .(11)Na^(23) ...

A positron is emitted from `._(11)Na^(23)` . The ratio of the atomic mass and atomic number of the resulting nuclide is

A

`22/10`

B

`22/11`

C

`23/10`

D

`23/12`

Text Solution

Verified by Experts

The correct Answer is:
c
During positron emmision, proton converts into neutron, there fore atomic no. decreases by one but mass number remains constant.
`""_(11)""^(23)Nato""_(10)""^(23)Ne+""_(0)""^(+1)e`
