What are the 4 types of radioactive decay?

Radioactive decay involves the emission of a particle and/or energy as one atom changes into another. In most instances, the atom changes its identity to become a new element. There are four different types of emissions that occur: alpha, beta, gamma, and positron emissions.

How to solve radioactive decay formula?

Use the half life radioactive decay formula: T 1 / 2 = 0.693 , but do not forget to convert numbers to SI units. Use the formula: d N ( t ) d t = N ( t ) where d N ( t ) d t = 0.255 s 1 . Use the radioactive decay formula: N ( t ) = N ( 0 ) e t where N(t)/N(0)=0.379, so:

What type of decay does AM 241 undergo to become NP 237: a alpha decay c positron emission b beta decay d electron capture?

For example, when Americium-241 undergoes alpha decay, it emits an alpha particle, resulting in Neptunium-237, with a decreased atomic number from 95 to 93 and a mass number reduction from 241 to 237.
