Element Lab Part 2 Checkpoint

Element Lab Part 2: Stuff From Stars Checkpoint

Make sure you have your completed "Element Lab Part 2: Stuff From Stars" open and available to use as a resource for this checkpoint. Read the slides and complete the embedded questions

Multiple Choice

Why are stars considered element factories?

• because elements come from planets

• because stars create elements

• because they have workers

Multiple Choice

At which stage do stars release the elements into the universe?

• nebula - (star birth)

• main sequence - (like our sun)

• supernova - (star death)

Multiple Choice

True or False: We are all made of elements produced from stars. We are made of star stuff!

• True

• False

Elements Are Pure Substances

• Elements are pure substances made of ONE kind of atom.

• A compound, such as H20 (water) is made of multiple elements.

Multiple Choice

Helium is a(n):

• Compound

• Element

• Atomic number

• Atomic Mass

Multiple Choice

Water is a(n):

• Compound

• Element

• Atomic number

• Atomic Mass

Multiple Choice

Carbon Dioxide is a(n):

• Compound

• Element

• Atomic number

• Atomic Mass

Multiple Select

Which TWO elements make up Carbon Dioxide?

(select TWO)

• Carbon

• Hydrogen

• Oxygen

• Nitrogen

Atomic Structure

• Atoms are made up of 3 types of subatomic particles: Protons, neutrons, and electrons.

• Protons and neutrons are found in the nucleus, while electrons orbit around the nucleus.

• The number of protons determines the type of element that exists.

Use your answers from Part 2 on your doc and the "Element Builder" Gizmo to help you answer the following questions

Multiple Select

Which TWO subatomic particles are located in the nucleus of an atom?

(Select TWO)

• Protons

• Neutrons

• Electrons

• None of the above

Multiple Choice

Which particles orbit around the outside of the nucleus?

• Protons

• Neutrons

• Electrons

• None of the above

Multiple Choice

Adding which subatomic particle caused the name of the element to change in the simulation?

• Protons

• Neutrons

• Electrons

• None of the above

Multiple Select

Our sun is composed mostly of which TWO elements?

(Select TWO)

• Carbon

• Hydrogen

• Oxygen

• Helium

Multiple Select

Which of the following statements are TRUE of the relationship between protons and elements? **Select all that apply**

• The number of protons determines the type of element

• The atomic number represents the number of protons in an atom

• The number of protons equals the number of electrons plus the number of neutrons.
