Question

Question 9 of 25Which items below describe beta decay?Check all that apply.A. A neutron turns into a proton.B. An atom is unstable.C. A proton turns into an electron.D. An electron is taken into the nucleus.

Answer 1

Given:

A beta decay process.

To find:

A process that describes beta decay.

Step-by-step explanation:

Beta decay is a radioactive decay in which an electron is emitted from an atom. There are two types of beta decay, beta plus decay and beta minus decay.

Beta plus decay: In beta plus decay, a proton inside a radioactive nucleus is converted into a neutron by giving out a positron and an electron neutrino.

Beta minus decay: In beta minus decay, a neutron is converted into a proton by giving out an electron and an electron antineutrino.

Thus, the correct option is option A.

Final answer:

The correct option is option A: a neutron turns into a proton.
