What do an electron and a neutron have in common?

Question

Each particle has a mass of 1 amu.
Each particle exists inside an atom.
Each particle has an electrical charge.
Each particle is located in the nucleus.

Answer 1

The statement "Each particle exists inside an atom" is true for both an electron and a neutron. However, the other statements are not accurate.

1. Each particle has a mass of 1 amu: This is incorrect. A neutron has a mass of approximately 1 amu (atomic mass unit), while an electron has a much smaller mass, approximately 1/1836 of an amu.

2. Each particle has an electrical charge: This is also incorrect. A neutron is electrically neutral (no charge), while an electron carries a negative charge.

3. Each particle is located in the nucleus: This is incorrect as well. Neutrons are located in the nucleus of an atom, whereas electrons are found in the electron cloud surrounding the nucleus.

Thus, the correct statement about what an electron and a neutron have in common is that each particle exists inside an atom.
