Question 1

What does the Bohr model explain about the structure of an atom?

Accepted Answer

Electrons orbit the nucleus in defined paths

Answer

Electrons are randomly distributed around the nucleus

Answer

Electrons are in an immeasurable cloud around the nucleus

Answer

Electrons do not exist in defined paths

Question 2

In the Bohr model, what happens when an electron gains energy?

Accepted Answer

It moves to a higher energy level

Answer

It loses energy and falls closer to the nucleus

Answer

It is ejected from the atom

Answer

It remains in the same energy level

Question 3

Which particle in the atom is located in the nucleus according to the Bohr model?

Accepted Answer

Proton

Answer

Electron

Answer

Neutron

Answer

Ionic

Question 4

What is the main limitation of the Bohr model?

Accepted Answer

It cannot accurately explain the spectra of atoms with more than one electron

Answer

It incorrectly states that electrons are in fixed orbits

Answer

It does not include a nucleus

Answer

It suggests that electrons have no mass

Question 5

According to the Bohr model, what role does the nucleus play in the atom?

Accepted Answer

It is the center where protons and neutrons are located

Answer

It houses only electrons

Answer

It has no effect on electron behavior

Answer

It is an empty space where electrons move

Question 6

What did Niels Bohr use to explain the energy levels of electrons?

Accepted Answer

Quantized energy levels

Answer

Random energy levels

Answer

Unstable energy levels

Answer

Continuous energy levels

Question 7

What did Bohr suggest about the emission of light from an atom?

Accepted Answer

Light is emitted when an electron transitions between energy levels

Answer

Light is emitted when electrons collide with protons

Answer

Light is always present in the atom

Answer

Light is absorbed but never emitted

Question 8

In the Bohr model, what defines the different energy levels for electrons?

Accepted Answer

The distance from the nucleus

Answer

The temperature of the atom

Answer

The size of the electrons

Answer

The type of atom

Question 9

What happens when an electron falls from a higher energy level to a lower energy level in the Bohr model?

Accepted Answer

A photon of light is emitted

Answer

The atom becomes ionized

Answer

The nucleons gain energy

Answer

An electron is created

Question 10

What is the fundamental concept introduced by the Bohr model regarding electron movement?

Accepted Answer

Electrons travel in specific, fixed orbits around the nucleus

Answer

Electrons can be found anywhere in the atom at all times

Answer

Electrons move randomly without any defined paths

Answer

Electrons are found only in the nucleus
