Closely examine the diagram representing the alpha decay of sodium-20 and draw the missing nucleus.
Solution 99P:
Here we are going to draw the the alpha decay of sodium-20 and the missing nucleus.
Step 1:
No. protons in Na-20 = 11
No. of neutrons in Na-20 = 9
After the emission of alpha- decay, it converts to Fluorine-16
Fluorine-16 , has no. of protons = 9
No. of neutrons =16-9 = 7
Step2:
The representing the alpha decay of sodium-20 and the missing nucleus is as follows:
