question 31

Multiple Choice

Regarding the charges of the electron, proton and neutron:

• A) the proton has a positive charge, the electron has a negative charge whose strength is equal to the strength of the proton's charge, and the neutron has no charge.
• B) the electron has a negative charge, the proton has a positive charge, and the neutron has a charge that can be positive or negative or zero depending on the ionization of the atom in which it resides.
• C) the proton has a positive charge, the electron has a much smaller negative charge, and the neutron has no charge.
• D) the proton has a positive charge, the neutron has a negative charge whose strength is equal to that of the proton's charge, and the electron has no charge.
• E) these objects are charged only when they reside in an ionized atom; otherwise, all three are uncharged.
