Question

and one atom of an plomonex has I clectron in its third shell cid state its electronic configural X ciz state the number of paralons (if in one atom af x of cilin its the mass humber of x is 23 how many how many of heertrons are peresent in one atom​

Answer 1

Answer:

During K electron capture, the atomic number decreases by 1 and the mass number remains unchanged.

The balanced reaction is Be47 + e−10 → Li37.

So, for the nuclide formed, atomic number = 3 and mass number = 7.
