Question

indicate whether each of the following describes a proton, neutron, electron, or none of these.
1 about 0 amu, +1
2 about 1 amu, no charge
3 about 0.0005 amu, -1
4 about 1 amu, -1

a. proton b. neutron c. electron d. none of these
e. qanon f. instagram g. magagram

Explanation:

1. Protons have a mass of about 1 amu and a charge of +1. The description "about 0 amu, +1" does not match any of the main sub - atomic particles, so it's none of these.
2. Neutrons have a mass of about 1 amu and no charge, so this describes a neutron.
3. Electrons have a mass of about 0.0005 amu and a charge of - 1, so this describes an electron.
4. There is no sub - atomic particle with a mass of about 1 amu and a charge of - 1, so it's none of these.

Answer:

1. D. none of these
2. B. neutron
3. C. electron
4. D. none of these
