Question

use the equation to answer the question. (_{6}^{10}c
ightarrow_{5}^{10}b + _{+1}^{0}e). a student claims that the equation models beta - minus decay because the atomic number of the nucleus decreases by one. in 1 - 2 sentences, explain the error in the students reasoning and what the model actually represents. (2 points)

Explanation:

Beta - minus decay involves a neutron in the nucleus changing into a proton, an electron, and an antineutrino. In the given equation, the atomic number should increase by 1 (not decrease) as a neutron turns into a proton. The student misinterpreted the change in atomic number.

Answer:

The student is wrong because in beta - minus decay, the atomic number of the nucleus increases by 1, not decreases, as a neutron is converted into a proton, an electron, and an antineutrino.
