Problem 30P

Which statements are consistent with Rutherford's nuclear theory as it was originally stated? Explain your answers.

(a) Atomic nuclei are small compared to the size of atoms.

(b) The volume of an atom is mostly empty space.

(c) Neutral potassium atoms contain more protons than electrons.

(d) Neutral potassium atoms contain more neutrons than protons.

Step-by-Step Solution:

Solution 30P

Here, we are going to find which of the given statements are consistent with Rutherford’s nuclear theory.

Step 1:

Rutherford designed an experiment to know how the electrons were arranged inside an atom. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil.

On the basis of his experiment, Rutherford put forward the nuclear model of an atom, which had the following features:

There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus.The electrons revolve around the nucleus in well-defined orbits. The size of the nucleus is very small as compared to the size of the atom.
