Which of the following is the basic unit of matter?
-
Atom
-
Proton
-
Neutron
-
Electron
Correct Answer
A. AtomExplanation
An atom is the basic unit of matter. It is the smallest particle of an element that retains the chemical properties of that element. Atoms consist of a nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Together, these subatomic particles make up the atom, which is the fundamental building block of all matter in the universe.Rate this question:

2. Which of the following is a subatomic particle that has a negative charge?
-
Atom
-
Electron
-
Neutron
-
Proton
Correct Answer
A. ElectronExplanation
An electron is a subatomic particle that has a negative charge. It is one of the fundamental particles that make up an atom. Electrons orbit around the nucleus of an atom and are responsible for the electrical properties of matter. They play a crucial role in chemical reactions and the formation of chemical bonds.Rate this question:

Which of the following subatomic particles has a positive charge?
-
Atom
-
Electron
-
Neutron
-
Proton
Correct Answer
A. ProtonExplanation
Protons are subatomic particles that have a positive charge. They are found in the nucleus of an atom along with neutrons, which have no charge. Electrons, on the other hand, have a negative charge and orbit around the nucleus. Therefore, the correct answer is proton.Rate this question:

Based on your class work, which of the following are the differences of Carbon 12 and Carbon 14?
-
Number of electrons
-
Number of protons
-
Number of neutrons
-
Atomic Number
Correct Answer
A. Number of neutronsExplanation
Carbon 12 and Carbon 14 are isotopes of carbon. The only difference between them is the number of neutrons in their nuclei. Carbon 12 has 6 neutrons, while Carbon 14 has 8 neutrons. The number of electrons, protons, and the atomic number remain the same for both isotopes, as they are determined by the element itself.Rate this question:

Which of the following are the same among Carbon-12, Carbon-13, and Carbon-14?
-
Number of electrons and protons
-
Atomic mass
-
Number of neutrons and protons
-
Atomic number only
Correct Answer
A. Number of electrons and protonsExplanation
The number of electrons and protons are the same among Carbon-12, Carbon-13, and Carbon-14. This is because the atomic number of an element determines the number of protons in its nucleus, and since carbon has an atomic number of 6, all isotopes of carbon will have 6 protons. Additionally, in a neutral atom, the number of electrons is equal to the number of protons. Therefore, the number of electrons and protons will be the same in all three carbon isotopes.Rate this question:

Ionic bond forms when one or more lectrons are transferred from one atom to another.
-
True
-
False
Correct Answer
A. TrueExplanation
Ionic bond forms when one or more electrons are transferred from one atom to another. This is because in an ionic bond, one atom donates electrons to another atom, resulting in the formation of positively charged ions and negatively charged ions. These oppositely charged ions are then attracted to each other, creating a strong bond. Therefore, the statement "Ionic bond forms when one or more electrons are transferred from one atom to another" is true.Rate this question:

An atom that loses an electron becomes negatively charged.
-
True
-
False
Correct Answer
A. FalseExplanation
When an atom loses an electron, it actually becomes positively charged, not negatively charged. This is because electrons have a negative charge, so when an atom loses one, it has an excess of positively charged protons in its nucleus, resulting in a net positive charge.Rate this question:

An atom that gains electron becomes negatively charged.
-
True
-
False
Correct Answer
A. TrueExplanation
When an atom gains an electron, it becomes negatively charged because electrons have a negative charge. The atom now has more negatively charged electrons than positively charged protons, resulting in an overall negative charge. This process is known as gaining an electron or gaining a negative charge.Rate this question:

The structure formed by atoms joined by covalet bonds is called a (an)
-
Element
-
Atom
-
Molecule
-
Compound
Correct Answer
A. MoleculeExplanation
A molecule is formed when atoms are joined together by covalent bonds. Covalent bonds involve the sharing of electrons between atoms, resulting in the formation of stable structures. In a molecule, the atoms are held together by these shared electrons, creating a distinct entity with its own set of chemical properties. Therefore, the correct answer is molecule.Rate this question:

The figure shows an atom of Lithium. Based on the figure, what is Lithium's atomic number?
-
3
-
6
-
7
-
10
Correct Answer
A. 3Explanation
The atomic number of an element represents the number of protons in the nucleus of an atom. In the given figure, the atom of Lithium is shown, and it has three protons in its nucleus. Therefore, the atomic number of Lithium is 3.Rate this question:

-
11
-
12
-
23
-

What is the number of neutrons of the atom represented by the following figure?
-
11
-
12
-
23
-
34
Correct Answer
A. 12Explanation
The number of neutrons in an atom is determined by subtracting the atomic number (which represents the number of protons) from the atomic mass. In this case, the atomic number is not given, but the answer is 12. Since the atomic number is not provided, we cannot calculate the number of neutrons accurately.Rate this question:

What is the atomic mass of the atom represented by the following figure?
-
11
-
12
-
23
-
34
Correct Answer
A. 23Explanation
The atomic mass of an atom is the total mass of all its protons, neutrons, and electrons. In the given figure, the number 23 represents the atomic mass. This means that the atom has a total of 23 protons, neutrons, and electrons combined.Rate this question:
