Question

a nuclide of 64/29 cu absorbs a positron. witch is the resulting atom? (A) 65/29Cu (B) 63/29 CU (C) 64/28Ni (D) 64/30 Zn

Answer 1

D

Step-by-step explanation:

Answer 2

Answer : Option D)
`Zn^(64)_(30)`

Explanation : When a positron is getting absorbed it means it will be
`e^(+1)_(0)` so, the
`Cu^(64)_(29)` will get converted;

So, the whole reaction will be;

`Cu^(64)_(29)` +
`e^(+1)_(0)` ---->
`Zn^(64)_(30)`.

This will convert the whole element of Cu will get changed into Zn. As, it absorbs by the positron, the atomic number gets increased from 29 to 30.
