alpha decay is an emission of ₂⁴He
nucleus. If an element undergoes an alpha decay, the mass of the daughter
nucleus formed is reduced by 4 compared to mass of parent atom and atomic
number is reduced by 2 compared to atomic number of parent atom.
Let's assume that the parent atom is X, atomic number is z and mass number is A. Then the formed daughter nucleus, Y should have atomic number as z-2 and mass number as A-4.
The equation is
(z) (A)X → ₂⁴α + (z-2)(A-4)Y
Example:
₉₄²³⁹Pu → ₂⁴α + ₉₂<span>²³⁵U</span>

<u>Answer:</u> The amount of element X remain after 40 years is 18.75 grams
<u>Explanation:</u>
We are given:
Total time period = 40 years
One half life = 10 years
Calculating the number of half lives,
To calculate the amount of element X after 4 half lives, we use the equation:
where,
a = amount of X after n-half lives
= initial amount of X = 300 g
n = number of half lives = 4
Putting values in above equation, we get:
Hence, the amount of element X remain after 40 years is 18.75 grams
