Bohr Diagram Questions and Answers Questions and Answers
- 1.
Which one of the following orbits around the nucleus?
- A.
Neutron
- B.
Electron
- C.
Proton
- D.
All of these
Correct Answer
B. ElectronExplanation
Electron is the correct answer because it is a subatomic particle that carries a negative charge and is found in the electron cloud surrounding the nucleus of an atom. Neutrons and protons, on the other hand, are located within the nucleus and do not orbit around it. Therefore, only the electron orbits around the nucleus.Rate this question:

The atomic mass is which of the following added together?
- A.
Electrons + Neutrons
- B.
Protons + Electrons
- C.
Atomic Number + Protons
- D.
Protons + Neutrons
Correct Answer
D. Protons + NeutronsExplanation
The atomic mass of an atom is determined by the sum of its protons and neutrons. Protons have a positive charge and are found in the nucleus of an atom, while neutrons have no charge and are also located in the nucleus. Electrons, on the other hand, have a negative charge and are found in the electron cloud surrounding the nucleus. Therefore, the correct answer is Protons + Neutrons.Rate this question:

An atom which has a charge due to losing or gaining electrons is called a/an
- A.
Electron
- B.
Proton
- C.
Neutron
- D.
Ion
Correct Answer
D. IonExplanation
An atom which has a charge due to losing or gaining electrons is called an ion. When an atom gains or loses electrons, it becomes electrically charged and forms an ion. This charge can be positive if the atom loses electrons or negative if the atom gains electrons. Ions play a crucial role in chemical reactions and the formation of compounds.Rate this question:

Which two elements are combined in order to make the ionic compound CaO?
- A.
Calcium, Oxygen
- B.
Carbon, Osmium
- C.
Carbon, Oxygen
- D.
Calcium, Osmium
Correct Answer
A. Calcium, OxygenExplanation
Calcium and oxygen are combined to form the ionic compound CaO. In an ionic compound, one element donates electrons to another element, resulting in the formation of positively and negatively charged ions. In this case, calcium donates two electrons to oxygen, which accepts them, forming Ca 2+ and O2- ions. These ions then attract each other due to their opposite charges, resulting in the formation of the ionic compound CaO.Rate this question:

What three numbers are always the same in a neutral atom?
- A.
Protons, Neutrons , Electrons
- B.
Protons, Neutrons, Mass number
- C.
Atomic number, Protons, Electrons
- D.
Mass number, Protons , Neutrons
Correct Answer
C. Atomic number, Protons, ElectronsExplanation
The atomic number represents the number of protons in an atom, which is a fundamental property of an element and remains constant for all atoms of the same element. Protons are positively charged particles found in the nucleus of an atom, and electrons are negatively charged particles that orbit around the nucleus. Therefore, the atomic number, the number of protons, and the number of electrons are always the same for neutral atoms of a given element.Rate this question:

When the electron is further from the _________ the greater the electrons energy.
Correct Answer
Nucleus, nucleusExplanation
The closer an electron is to the nucleus, the stronger the attractive force between them, resulting in lower energy levels for the electron. As the electron moves further away from the nucleus, the attractive force weakens, allowing the electron to have higher energy levels. Therefore, when the electron is further from the nucleus, its energy is greater.Rate this question:
- 7.
Heat, light or energy can ________ an electron and move it to an orbit further from the nucleus.
Correct Answer
excite, ExciteExplanation
When an electron is excited, it gains energy and moves to an orbit further from the nucleus. This can be achieved by adding heat, light, or any other form of energy to the electron.Rate this question:

Bohr’s model was based on what?
- A.
The emission spectra of hydrogen
- B.
Dual nature of matter
- C.
Discharging of elements
- D.
All of these
Correct Answer
A. The emission spectra of hydrogenExplanation
Bohr's model was based on the emission spectra of hydrogen. This means that he studied the specific wavelengths of light emitted by hydrogen atoms when they transitioned from higher energy levels to lower energy levels. By analyzing these spectra, Bohr was able to propose his model of the atom, which included the concept of energy levels and electrons orbiting the nucleus in specific orbits. This model was a significant advancement in understanding atomic structure and laid the foundation for further developments in quantum mechanics.Rate this question:

If an atom contains exactly 79 protons, then it's an atom of what element?
- A.
Silver
- B.
Gold
- C.
Nitrogen
- D.
Lithium
Correct Answer
B. GoldExplanation
An atom with exactly 79 protons is an atom of gold. The number of protons in an atom determines its atomic number, which is unique to each element. Gold has an atomic number of 79, so an atom with 79 protons can only be gold.Rate this question:

What is the maximum number of electrons in the first shell in the Bohr model of the atom?
- A.
2
- B.
3
- C.
4
- D.
5
Correct Answer
A. 2Explanation
According to the Bohr model of the atom, the first shell can hold a maximum of 2 electrons. This is because the first shell has only one subshell, which is the s subshell, and it can accommodate a maximum of 2 electrons.Rate this question:
