Question

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. What other characteristic does the radiation have?

Answer 1

Answer : some shielding required

Step-by-step explanation:

Answer 2

Answer: The radiation emitted will have negligible mass number.

Step-by-step explanation:

Radioactive decay is defined as the process in which an unstable nuclei breaks down into stable nuclei via various methods.

An isotope undergoes a radioactive decay to attain stability.

There are three types of decay process, but the process in which the emitted radiation carries a charge of -1 is beta decay.

Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron. In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units. The released beta particle is also known as electron.

`_Z^A\textrm{X}\rightarrow _(Z+1)^A\textrm{Y}+_(-1)^0\beta`

Hence, the radiation emitted will have negligible mass number.
