Question

11. Chemist Ernest Rutherford performed the gold foil experiment in which he concluded the

atom is mostly empty space, with a small, dense, positively charged center. Rutherford's
discovery of the proton did not fully account for the entire mass of the atom. Which is an
example of research that extended Rutherford's findings?
a. De Broglie viewed electrons exhibiting wave-like behavior.
b. Bohr concluded that electrons orbit the nucleus in set circular paths.
c. Chadwick determined the charge of the neutron to be neutral and its mass similar to
that of a proton.
d. Thomson determined that the atom consists of negatively-charged particles.

Answer 1

c. Chadwick determined the charge of the neutron to be neutral and its mass similar to that of a proton.

Step-by-step explanation:

The research that furthered Rutherford's work is the discovery made by James Chadwick who determined the nature of neutron.

• Rutherford was inadequate to characterized the composition of the nucleus.
• This furthered the curiosity of Chadwick by which he discovered the neutrons.
• The mass of the neutrons is similar to that of the protons
• Together they account for the mass number of the atom.
• The neutrons do not carry any charges on them.
