Answer 1

The type of Nuclear decay that is described where Gold undergoes transmutation is given as 185/79 Au → 181/77 Ir + 4/2 He, it is called Alpha Decay.

What are the characteristics of Alpha Decay?

An Alpha Decay can be described as a form of radioactive or Nuclear decay where the atomic nucleus releases an alpha particle (also known as Helium Nucleus).

It then converts into a nucleus that is atomic with an atomic number of two and a mass number of four.

Alpha Decay is usually trigged for two key reasons:

• An unstable nucleus; and
• excessive protons.
