9th Grade: Trivia Quiz On Basic Atomic Chemistry! - Quiz

A quiz for those who have just been introduced to the basics of atomic chemistry.

Questions and Answers

1.

Which of the following would not be found in the structure of all atoms?
- A.
  
  Electrons
- B.
  
  Protons
- C.
  
  Chromosomes
- D.
  
  Neutrons
Correct Answer
C. Chromosomes

Explanation
Chromosomes would not be found in the structure of all atoms because chromosomes are only present in the nucleus of eukaryotic cells, which are not part of the atomic structure. Atoms consist of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus. Chromosomes, on the other hand, are structures that contain DNA and are responsible for carrying genetic information in living organisms. They are not present in atoms.

Which particles are located on shells orbiting the nucleus of atoms?
- A.
  
  Electrons
- B.
  
  Protons
- C.
  
  Neutrons
Correct Answer
A. Electrons

Explanation
Electrons are located on shells orbiting the nucleus of atoms. Protons and neutrons, on the other hand, are located within the nucleus itself. Electrons are negatively charged particles that occupy specific energy levels or shells around the nucleus. These shells determine the electron's distance from the nucleus and play a crucial role in chemical bonding and the overall stability of the atom.

How many electrons does Sodium have?
- A.
  
  12
- B.
  
  23
- C.
  
  11
- D.
  
  44
Correct Answer
C. 11

Explanation
Sodium has 11 electrons. This is because the atomic number of sodium is 11, which represents the number of protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, so sodium also has 11 electrons.

Which atoms has 12 electrons?
- A.
  
  Carbon
- B.
  
  Lithium
- C.
  
  Magnesium
- D.
  
  Oxygen
Correct Answer
C. Magnesium

Explanation
Magnesium has 12 electrons because it is located in Group 2 of the periodic table, which means it has 2 valence electrons and 10 core electrons. The atomic number of magnesium is 12, indicating that it has 12 protons and therefore 12 electrons in a neutral atom.

Which atom has an electronic configuration of 2, 5?
- A.
  
  Boron
- B.
  
  Lithium
- C.
  
  Carbon
- D.
  
  Nitrogen
Correct Answer
D. Nitrogen

Explanation
Nitrogen is the correct answer because it has an atomic number of 7, which means it has 7 electrons. The electronic configuration of 2, 5 indicates that there are 2 electrons in the first energy level and 5 electrons in the second energy level, which matches the electronic configuration of nitrogen.

Potassium has and electronic configuration of?
- A.
  
  2, 8,1
- B.
  
  2, 8, 7
- C.
  
  2, 8, 8, 1
- D.
  
  2, 8, 5
Correct Answer
C. 2, 8, 8, 1

Explanation
The correct answer is 2, 8, 8, 1. This is because the atomic number of potassium is 19, which means it has 19 electrons. The electronic configuration represents the distribution of these electrons in different energy levels or shells. The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons as well. Therefore, the electronic configuration of potassium is 2, 8, 8, 1.

The atomic particles that are positively charged are?
- A.
  
  Protons
- B.
  
  Electrons
- C.
  
  Neutrons
Correct Answer
A. Protons

Explanation
Protons are atomic particles that carry a positive charge. They are found in the nucleus of an atom and are equal in number to the number of electrons in a neutral atom. Electrons, on the other hand, are negatively charged and orbit around the nucleus. Neutrons have no charge and are also found in the nucleus. Therefore, the correct answer is protons.

The atomic particles that have no charge are?
- A.
  
  Electrons
- B.
  
  Protons
- C.
  
  Neutrons
Correct Answer
C. Neutrons

Explanation
Neutrons are atomic particles that have no charge. Unlike electrons, which carry a negative charge, and protons, which carry a positive charge, neutrons are electrically neutral. They are found in the nucleus of an atom along with protons, and their main role is to contribute to the mass of the atom without affecting its overall charge.

  Protons
- C.
  
  Electrons
Correct Answer
C. Electrons

Explanation
Electrons are the atomic particles that are negatively charged. They orbit around the nucleus of an atom and carry a negative electrical charge. Neutrons, on the other hand, have no charge, while protons carry a positive charge. Therefore, electrons are the correct answer in this case.
