neutral - no charge

positive

negative

neutrino

Multiple Choice

Two atomic nuclei in MOST situations would

Attract each other

Repel each other

Randomly fuse together

Multiple Choice

What are some of the outcomes of nuclear fusion?

Produce larger materials from the collision of smaller materials.

Release energy.

Produce smaller materials from the collision of larger materials.

Produce more massive materials from the collision of less massive materials & Release energy

Match

Match the following fusion reaction diagrams and explanations.

Proton-Proton chain reaction of H to He

Hydrogen fuses to create deuterium

Heium-3 fusion to create Helium-4

Helium-4 fuses to create Carbon-12

Deuterium fuses to create Helium-3

Multiple Choice

Why does helium sink to the middle of the core?

Helium has more mass

Helium has less mass

It doesn't

Multiple Choice

__________________ is the process in which two or more smaller nuclei combine to create a larger, more stable nuclei.

Nuclear Decay

Nuclear Fission

Nuclear Fusion

None of the above

Multiple Choice

During nuclear fusion in the sun, energy is released in the form of ____.

Light and Heat

Sound and Light

Heat and Sound

Light and Electricity

Multiple Choice

Why does nuclear fusion require high pressures and temperatures?

To provide enough energy to split the nucleus.

The two nuclei are both negatively charged and repel each other.

To lower the cost.

To overcome the electromagnetic repulsion of the nuclei.

Multiple Choice

In nuclear fusion, less massive atoms are forced together to create more massive atoms. Does this process release, absorb or maintain energy?

Absorb energy

Maintain energy

Release energy

Multiple Choice

The process of forming elements is known as

generation

nucleosynthesis

genesis

synthesis

Dropdown

"Nuclear fusion" refers to the process of

light nuclei merging to form a heavier

. An example is the combination of 2 protons (hydrogen atoms) to create deuterium.

"Stellar Nucleosynthesis" describes the

process of creating elements within stars through a series of nuclear fusion reactions, leading to the production of

elements like carbon, oxygen, and iron from

elements like hydrogen.

Multiple Choice

Where does nuclear fusion occur in the sun?

Surface

Corona

Core

Convective zone
