Question

protons and neutrons are found in the nucleus of an atom. traveling around the nucleus are fast-moving particles called electrons. each electron has a negative electrical charge. an electron is much smaller and lighter than a proton or a neutron. which of the following statements are true? select all that apply. an electron has a negative electrical charge. a proton is much bigger and heavier than an electron. all of an atoms electrons are located inside its nucleus.

Explanation:

1. For the statement "An electron has a negative electrical charge": The passage clearly states "Each electron has a negative electrical charge", so this is true.
2. For the statement "A proton is much bigger and heavier than an electron": The passage says "An electron is much smaller and lighter than a proton or a neutron", which implies a proton is bigger and heavier than an electron, so this is true.
3. For the statement "All of an atom's electrons are located inside its nucleus": The passage says "Traveling around the nucleus are fast - moving particles called electrons", so electrons are around the nucleus, not inside. This statement is false.

Answer:

A. An electron has a negative electrical charge.
B. A proton is much bigger and heavier than an electron.
