Question

Which type of radiation consists of a fast stream of negatively charged particles?

Answer 1

Beta decay

Step-by-step explanation:

Beta radiation consists of a fast stream of negatively charged particles. The particles that are formed by the process of beta radiation are beta particles. These particles are electron and positron. There are two forms of beta decay :

1.
`\beta^-\ decay`

2.
`\beta^+\ decay`

In minus beta decay, a neutron is turned into a proton, an electron and anti neutrino. While in plus beta decay, a proton is turned into neutron, positron and neutrino.

Hence, the correct answer is beta decay.

Answer 2

The answer is Beta Radiation via emission of beta particles. Beta particles are negatively charged particles whilst alpha radiation are using positively charged particles.
