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 the same size as an electron. all of an atoms electrons are located outside its nucleus.

Explanation:

• The first statement is true as the text explicitly says "Each electron has a negative electrical charge".
• The second statement is false because the text states "An electron is much smaller and lighter than a proton or a neutron".
• The third statement is true since the text mentions "Traveling around the nucleus are fast - moving particles called electrons", implying they are outside the nucleus.

Answer:

• An electron has a negative electrical charge.
• All of an atom's electrons are located outside its nucleus.
