Question

Does anyone knows how to solve this??

Answer 1

²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He

Step-by-step explanation:

In alpha decay;

The mass number decreases by 4

Atomic Number decreases by 2

Mass Number = 243 - 4 = 239

Atomic Number = 95 - 2 =93

Element = Neptunium (Np)

Equation for the decay is given as;

²⁴³₉₅Am --> ²³⁹₉₃Np + ⁴₂He
