Atomic Structure and Isotopes

The video tutorial guides students through completing a Gizmos assignment. It covers accessing classwork and resources, using a Google Form for the assignment, and navigating the Gizmos platform. The tutorial explains elements, compounds, and atomic structures, and demonstrates using the Element Builder Gizmo to build atoms. It also explores isotopes, stability, and atomic symbols, providing a comprehensive understanding of the topic.

Where can you find the Gizmos assignment if you haven't completed it?

• Under the 'Completed' section

• In the 'Plans' section

• In the 'Archived' section

• On the main dashboard

What is the purpose of the Google Form in the Gizmos assignment?

• To answer questions related to the assignment

• To track time spent on the assignment

• To download additional resources

• To submit feedback

What distinguishes an element from a compound?

• Elements are always gases, while compounds are always solids.

• Elements are mixtures, while compounds are pure substances.

• Elements are made of one kind of atom, while compounds are made of two or more kinds of atoms.

• Elements are found in nature, while compounds are man-made.

What particles make up an atom?

• Protons, neutrons, and ions

• Protons, neutrons, and electrons

• Neutrons, electrons, and ions

• Protons, electrons, and ions

What happens when you add electrons to an atom in the element builder?

• They disappear

• They combine with protons

• They go to the nucleus

• They orbit around the nucleus

What is the atomic number of an element?

• The total number of subatomic particles

• The number of neutrons

• The number of protons

• The number of electrons

What is an isotope?

• An element with a different number of protons

• An element with a different number of electrons

• An element with a different number of neutrons

• An element with a different atomic number

How is an isotope represented?

• By its atomic number and symbol

• By its chemical formula

• By its mass number and atomic symbol

• By its electron configuration

What does it mean if an atom is neutral?

• It has no protons

• It has an equal number of protons and electrons

• It has more electrons than protons

• It has more protons than electrons

What happens to the atomic identity when protons are changed?

• The element remains the same

• The element becomes a compound

• The element changes to a different one

• The element becomes unstable
