  1. Atom

  2. Molecule

  3. Electron

  4. Neutron

Show answer
Correct Option: A
Explanation:

An atom is the smallest unit of matter that retains all the chemical properties of an element.

What are the three main subatomic particles?

  1. Protons, Neutrons, Electrons

  2. Quarks, Leptons, Bosons

  3. Mesons, Baryons, Hadrons

  4. Gluons, Photons, Gravitons

Show answer
Correct Option: A
Explanation:

Protons, neutrons, and electrons are the three main subatomic particles that make up atoms.

What is the atomic number of an element?

  1. Number of protons in the nucleus

  2. Number of neutrons in the nucleus

  3. Number of electrons in the nucleus

  4. Number of electrons in the outermost shell

Show answer
Correct Option: A
Explanation:

The atomic number of an element is equal to the number of protons in the nucleus of its atoms.

What is the mass number of an element?

  1. Number of protons in the nucleus

  2. Number of neutrons in the nucleus

  3. Number of electrons in the nucleus

  4. Number of electrons in the outermost shell

Show answer
Correct Option:
Explanation:

The mass number of an element is equal to the sum of the number of protons and neutrons in the nucleus of its atoms.

What is an isotope?

  1. Atoms of the same element with different atomic numbers

  2. Atoms of the same element with different mass numbers

  3. Atoms of different elements with the same atomic number

  4. Atoms of different elements with the same mass number

Show answer
Correct Option: B
Explanation:

Isotopes are atoms of the same element that have the same atomic number but different mass numbers.

What is the periodic table?

  1. A tabular arrangement of elements organized by atomic number

  2. A tabular arrangement of elements organized by mass number

  3. A tabular arrangement of elements organized by chemical properties

  4. A tabular arrangement of elements organized by physical properties

Show answer
Correct Option: A
Explanation:

The periodic table is a tabular arrangement of elements organized by their atomic numbers, with elements in the same group exhibiting similar chemical properties.

What is a chemical bond?

  1. The force that holds atoms together to form molecules or compounds

  2. The force that holds electrons in an atom

  3. The force that holds protons in an atom

  4. The force that holds neutrons in an atom

Show answer
Correct Option: A
Explanation:

A chemical bond is the force that holds atoms together to form molecules or compounds.

What are the three main types of chemical bonds?

  1. Ionic, Covalent, Metallic

  2. Hydrogen, Carbon, Nitrogen

  3. Solid, Liquid, Gas

  4. Acid, Base, Salt

Show answer
Correct Option: A
Explanation:

The three main types of chemical bonds are ionic, covalent, and metallic.

What is an ionic bond?

  1. A bond formed by the transfer of electrons from one atom to another

  2. A bond formed by the sharing of electrons between atoms

  3. A bond formed by the attraction between positively and negatively charged ions

  4. A bond formed by the attraction between two positively charged ions

Show answer
Correct Option: A
Explanation:

An ionic bond is a bond formed by the transfer of electrons from one atom to another.

What is a covalent bond?

  1. A bond formed by the transfer of electrons from one atom to another

  2. A bond formed by the sharing of electrons between atoms

  3. A bond formed by the attraction between positively and negatively charged ions

  4. A bond formed by the attraction between two positively charged ions

Show answer
Correct Option: B
Explanation:

A covalent bond is a bond formed by the sharing of electrons between atoms.

What is a metallic bond?

  1. A bond formed by the transfer of electrons from one atom to another

  2. A bond formed by the sharing of electrons between atoms

  3. A bond formed by the attraction between positively and negatively charged ions

  4. A bond formed by the attraction between positively charged ions and a sea of electrons

Show answer
Correct Option: D
Explanation:

A metallic bond is a bond formed by the attraction between positively charged ions and a sea of electrons.

What are the three states of matter?

  1. Solid, Liquid, Gas

  2. Plasma, Bose-Einstein Condensate, Fermionic Condensate

  3. Acid, Base, Salt

  4. Metal, Nonmetal, Metalloid

Show answer
Correct Option: A
Explanation:

The three states of matter are solid, liquid, and gas.

What is a solid?

  1. A state of matter in which the particles are fixed in a regular pattern

  2. A state of matter in which the particles are free to move around

  3. A state of matter in which the particles are attracted to each other but can still move around

  4. A state of matter in which the particles are repelled from each other

Show answer
Correct Option: A
Explanation:

A solid is a state of matter in which the particles are fixed in a regular pattern.

What is a liquid?

  1. A state of matter in which the particles are fixed in a regular pattern
