Atoms and Molecules Video

What are atoms?

• Tiny particles that make up matter

• The fundamental building blocks of energy

• Large structures that cannot be broken down

• Empty spaces between molecules

What is the main difference between elements on the periodic table?

• The number of protons in the nucleus

• The number of neutrons in the nucleus

• The number of electrons in the nucleus

• The number of quarks in the nucleus

What is the atomic number of an element?

• The number of protons in the nucleus

• The number of neutrons in the nucleus

• The number of electrons in the nucleus

• The number of quarks in the nucleus

What is the main difference between matter and energy?

• Matter is made up of atoms and molecules, while energy is not

• Matter is a solid, while energy is a liquid or gas

• Matter is visible, while energy is invisible

• Matter is made up of protons and neutrons, while energy is made up of electrons

What is the role of carbon in living things?

• Carbon is essential for the chemicals of living things

• Carbon is responsible for the production of energy in living things

• Carbon is a waste product in living things

• Carbon has no role in living things

What is the purpose of the giant machine used by nuclear physicists?

• To study the inside of atoms and the nucleus

• To generate electricity from atoms

• To create new elements

• To break down molecules into atoms

What is the main difference between atoms and molecules?

• Atoms are the smallest pieces of matter, while molecules are made up of atoms

• Atoms are made up of protons and neutrons, while molecules are made up of electrons

• Atoms are visible, while molecules are invisible

• Atoms are solid, while molecules are liquid or gas

What is the purpose of the periodic table?

• To organize and classify all the elements based on their properties

• To determine the atomic number of an element

• To study the motion of atoms

• To break down molecules into atoms

What is the main difference between protons and neutrons?

• Protons have a positive charge, while neutrons have no charge

• Protons have a negative charge, while neutrons have a positive charge

• Protons have no charge, while neutrons have a negative charge

• Protons and neutrons have the same charge

What is the role of electrons in an atom?

• They orbit around the nucleus

• They make up the nucleus

• They repel each other

• They are responsible for the production of energy
