Question

Carlos arranges his notes about radioactive decay in a graphic organizer. He wants to add the labels shown. Label 1: Photon Label 2: Positron Label 3: No change in mass number. Which is the best region for each label?

OPTION 1: Label 1: X Label 2: Z Label 3: Y
OPTION 2: Label 1: Y Label 2: X Label 3: Z
OPTION 3: Label 1: Z Label 2: Y Label 3: X
OPTION 4: Label 1: Z Label 2: X Label 3: Y

Answer 1

The best region for each label in Carlos' graphic organizer is: Label 1: Z, Label 2: X, Label 3: Y.

Step-by-step explanation:

The best region for each label in Carlos' graphic organizer is:

• Label 1: Z
• Label 2: X
• Label 3: Y

This can be determined by understanding the process of radioactive decay and the properties of the particles involved. Label 1 represents a photon, which is a high-energy photon or a gamma ray. This is associated with the emission of electromagnetic radiation and does not change the mass number or atomic number of the nucleus. Label 2 represents a positron, which is a particle with the same mass as an electron but a positive charge. This is associated with beta-plus decay, where a proton is converted into a neutron. Label 3 represents no change in mass number, which can occur in certain decay processes where only the atomic number changes.
