Question

Identify the conclusion(s) from the Rutherford's alpha ray scattering experiment.

• A. The centre of the atom is empty space
• B. Most of the volume of the atom is empty
• C. The center of the atom has only negative charge
• D. Atomic mass is concentrated at the centre of the atom

Answer 1

Answer: (B), (D)

The correct options are
B

Most of the volume of the atom is empty

D

Atomic mass is concentrated at the centre of the atom

According to Rutherford, the atoms are made of two parts: the nucleus and the extra-nuclear part. His experiments proved that the atom is largely empty and has a heavy positively-charged body at the centre called the nucleus. The central nucleus is positively-charged and the negatively-charged electrons revolve around the nucleus.
