Question

Which of the following is not true in Rutherford's nuclear model of atom
(a) Protons and neutrons are present inside nucleus
(b) Volume of nucleus is very small as compared to volume of atom
(c) The number of protons and neutrons are always equal
(d) The number of electrons and protons are always equal​

Answer 1

Answer:

volume of nucleus is very small as compared to volume of atom

Answer 2

Answer:

C) The number of protons is equal to the number of neutrons is the false statement. It’s the total number of electrons which is equal to that of protons.

Following are some properties:

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.

The number of protons in the nucleus of the atom is equal to the atomic number (Z).

The number of electrons in a neutral atom is equal to the number of protons.

The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
