Atomic Quiz: Protons, Neutrons, And Electrons
Atoms are the basic building blocks of ordinary matter. Play this informative atomic quiz about proton, neutrons, and electrons to gauge your chemistry knowledge. Atoms can join together and form molecules, which also join together to create the objects that we can see around us. Atoms are composed of particles called protons, electrons, and neutrons. Take up the test below and see how much you understand about them. Pick the letter you think is correct. All the best!
- 1.
Protons...
- A.
Are negatively charged
- B.
Orbit the nucleus
- C.
Are positively charged
- D.
1/2000 amu
Correct Answer
C. Are positively chargedExplanation
Protons are positively charged particles found in the nucleus of an atom. They have a charge of +1 and a mass of approximately 1 atomic mass unit (amu). Unlike electrons, which are negatively charged and orbit the nucleus, protons are in the nucleus. Therefore, the correct answer is that protons are positively charged.Rate this question:

Galena is an ore of?
- A.
Lead
- B.
Aluminum
- C.
Nickel
- D.
Uranium
Correct Answer
A. LeadExplanation
Galena is an ore of lead. It is a mineral composed primarily of lead sulfide and is the most important ore of lead. Galena is typically gray in color and has a metallic luster. It is commonly found in hydrothermal veins and is often associated with other minerals such as sphalerite and pyrite. Lead is extracted from galena through a process called smelting, where the ore is heated to a high temperature to separate the lead from other impurities. Lead is used in various industries, including construction, batteries, and ammunition.Rate this question:

Cryolite is an ore of?
- A.
Aluminium
- B.
Magnesium
- C.
Boron
- D.
Cobalt
Correct Answer
A. AluminiumExplanation
Cryolite is an ore of aluminum. This means that cryolite is a mineral that contains aluminum in a form that can be extracted and used for various purposes. Aluminum is a lightweight, silvery-white metal that is commonly used in industries such as construction, transportation, and packaging due to its low density, high strength, and corrosion resistance. Cryolite is an important source of aluminum because it contains a high concentration of the metal, making it economically viable to extract and process. Bauxite is another common aluminum ore.Rate this question:

Electrons...
- A.
Orbit the nucleus and are negatively charged
- B.
Are positively charged and make up the nucleus
- C.
Take up most of the mass in the atom
- D.
Are the same as the atomic number in atoms and ions
Correct Answer
A. Orbit the nucleus and are negatively chargedExplanation
Electrons orbit the nucleus and are negatively charged. This is a fundamental concept in atomic structure. Electrons are subatomic particles that have a negative charge and they revolve around the nucleus in specific energy levels or orbitals. The negatively charged electrons balance out the positive charge of the protons in the nucleus, resulting in an overall neutral atom. This arrangement of electrons in different energy levels determines the chemical properties and behavior of an element.Rate this question:

The nucleus
- A.
Is made up of protons and neutrons
- B.
Orbits the center proton
- C.
Is the coldest point in the atom
- D.
Surrounds the atom
Correct Answer
A. Is made up of protons and neutronsExplanation
The nucleus makes up most of the mass and is made up of protons and neutrons.Rate this question:

The atomic number
- A.
Tells what can and what cannot move in an atom
- B.
Orbits the center proton
- C.
States how many spoolas are in the nucleus
- D.
Is the same as the number of protons
Correct Answer
D. Is the same as the number of protonsExplanation
The atomic number of an atom refers to the number of protons in its nucleus. It determines the element's identity and is unique to each element. The number of protons also determines the number of electrons in a neutral atom, as atoms electrons have an equal and opposite charge to protons. Therefore, the statement "the atomic number is the same as the amount of protons" is correct.Rate this question:

AMU stands forÂ
- A.
Absolute Mass Unit
- B.
Atomic Making Unit
- C.
Atomic Mass Unit
- D.
Abraham's Mass Unit
Correct Answer
C. Atomic Mass UnitExplanation
AMU stands for Atomic Mass Unit. This unit is used to measure the mass of atoms and molecules. It is defined as one-twelfth the mass of a carbon-12 atom. The atomic mass unit is a convenient way to express the relative masses of different atoms and molecules. It allows scientists to compare the masses of particles and calculate molecular weights. Therefore, the correct answer is Atomic Mass Unit.Rate this question:

If the atomic number is 9, the number of protons is
- A.
8
- B.
9
- C.
1
- D.
12
Correct Answer
B. 9Explanation
The atomic number of an element represents the number of protons in the nucleus of an atom. Therefore, if the atomic number is 9, it means that there are 9 protons in the nucleus of the atom.Rate this question:

If Uranium's atomic number is 92 and it has 10 neutrons, how many protons does it have?
- A.
92
- B.
86
- C.
82
- D.
102
Correct Answer
A. 92Explanation
Uranium's atomic number represents the number of protons in its nucleus. Since the question states that Uranium has an atomic number of 92, it means that it has 92 protons. The number of neutrons is not relevant to determining the number of protons.Rate this question:

If Aluminum has an atomic number of 13 and has 14 neutrons, what is its mass?
- A.
25
- B.
1
- C.
32
- D.
27
Correct Answer
D. 27Explanation
The atomic number of an element represents the number of neutrons in its nucleus. In this case, Aluminum has an atomic number of 13, which means it has 13 protons. The mass of an element is the sum of its protons and neutrons. Since the question states that Aluminum has 13 protons and 14 neutrons the mass of Aluminum is 27 (13 protons + 14 neutrons).Rate this question:
