Understanding Atomic Structure Concepts

The video tutorial covers the structure of atoms, focusing on the masses, charges, and locations of protons, neutrons, and electrons. It introduces essential questions about atomic structure and explains how to determine the number of subatomic particles using the periodic table. The lesson concludes with an assignment for students to answer the essential questions.

Which of the following is NOT an essential question about atoms discussed in the lesson?

• What is an atom?

• What is an atom made of?

• What are the locations, masses, and charges of the subatomic particles?

• How do atoms form molecules?

What are the two basic components of an atom?

• Neutrons and Electrons

• Electron Cloud and Nucleus

• Protons and Neutrons

• Electrons and Protons

Which subatomic particle has a positive charge?

• Photon

• Proton

• Neutron

• Electron

Where are electrons located in an atom?

• In the neutron field

• In the electron cloud

• In the nucleus

• In the proton shell

What is the mass of a neutron?

• 0 amu

• 1 amu

• 2 amu

• 0.5 amu

What does the atomic number of an element represent?

• Number of neutrons

• Number of electrons

• Number of protons

• Atomic mass

In the APE-MAN acronym, what does 'APE' stand for?

• Atomic number equals protons equals electrons

• Atomic mass equals protons equals electrons

• Atomic number equals neutrons equals electrons

• Atomic mass equals neutrons equals electrons

How do you calculate the number of neutrons in an atom?

• Atomic number minus mass number

• Mass number minus atomic number

• Electrons minus protons

• Protons minus electrons

What information does each square on a periodic table provide?

• Only the atomic number

• Only the atomic mass

• Only the element symbol

• Atomic number, element symbol, and atomic mass

What are students instructed to do at the end of the lesson?

• Conduct an experiment on atomic structure

• Create a model of an atom

• Write and submit answers to the essential questions

• Memorize the periodic table
