What is the definition of "Mass"?

• Mass is the density of an object.
• Mass is the volume of an object.
• Mass is the weight of an object.
• A body of matter.

What is the definition of "Electron"?

• A neutral particle that exists outside the atom.
• A positively charged particle found in the nucleus of an atom.
• Small particles within the atom that have a negative charge.

• A type of chemical bond between atoms.

What is the definition of "Interact"?

• To react with one another.

• To observe without any engagement.
• To ignore someone completely.
• To only listen without responding.

What is the definition of "Proton"?

• A proton is a large particle found in the outer shell of an atom.
• A proton is a type of chemical bond between atoms.
• A proton is a negatively charged particle in the electron cloud.
• A subatomic particle that has a positive charge and is located in the nucleus of an atom.

What is the definition of "Atom"?

• An atom is a type of molecule.
• An atom is a form of energy.
• An atom is the smallest particle into which an element can be divided and still be the same.

• An atom is a large particle found in stars.

What is the definition of "Atomic Number"?

• The atomic number is the number of protons in the nucleus of an atom.
• The atomic number is the number of neutrons in the nucleus of an atom.
• The atomic number is the total number of electrons in an atom.
• The atomic number is the mass of an atom measured in atomic mass units.

What is the definition of "Neutron"?

• A neutron is a particle that exists outside the atom.
• A neutron is a type of electron that orbits the nucleus.
• A neutron is a positively charged particle in the nucleus of an atom.
• A neutron is a neutral subatomic particle that has no charge and is found in the nucleus of an atom.

What is the definition of "Indicate"?

• To suggest.

• To summarize or condense information.
• To confuse or mix up ideas.
• To ignore or overlook something.

What is the definition of "Electron Cloud"?

• The electron cloud is a solid structure surrounding the nucleus.
• The electron cloud is the center of an atom where protons are located.
• The electron cloud is the region around an atom's nucleus where electrons are likely to be found.
• The electron cloud refers to the fixed paths that electrons follow around the nucleus.

What is the definition of "Law of Conservation of Mass"?

• Mass is only conserved in physical changes, not chemical changes.
• The Law of Conservation of Mass states that in ordinary changes, mass isn't created or destroyed.

• Mass can be created or destroyed in chemical reactions.
• The total mass of reactants is always greater than the total mass of products.
