Question

In the Bohr model of the atom, which of the following statements best describes the difference between helium isotopes with a mass of 3 and helium isotopes with a mass of 4? a. Both helium isotopes have the same number of protons but different numbers of neutrons. b. Both helium isotopes have the same number of electrons but different numbers of protons. c. Both helium isotopes have the same number of neutrons but different numbers of electrons. d. Both helium isotopes have the same number of protons, electrons, and neutrons.

Answer 1

In the Bohr model of the atom, helium isotopes with a mass of 3 and 4 differ in the number of neutrons. They have the same number of protons and electrons.

Step-by-step explanation:

In the Bohr model of the atom, the difference between helium isotopes with a mass of 3 and helium isotopes with a mass of 4 is that they have different numbers of neutrons.

Helium isotopes with a mass of 3 have 1 neutron, while helium isotopes with a mass of 4 have 2 neutrons. Both isotopes have the same number of protons and electrons, which is 2.

So, the correct answer is a. Both helium isotopes have the same number of protons but different numbers of neutrons.
