Nuclear Science Concepts

Front

Difference between chemical and nuclear changes

Back

Chemical changes involve the rearrangement of atoms, while nuclear changes involve changes in the nucleus of an atom.

Front

Determining the most likely type of decay

Back

By comparing the neutron to proton ratio to the band of stability.

Front

Nuclear reactions involve protons and neutrons in the nucleus.

Back

Chemical reactions involve electrons (valence electrons).

Front

The ratio of neutrons to protons determines how radioactive a substance is.

Back

Front

Chemical reactions result in new compounds, but the elements remain the same.

Front

N/Z too low indicates what type of decay?

Back

Neutron-poor nuclei are likely to undergo positron emission or K-capture.

Front

Effect of positron emission or K-capture on neutron and proton numbers.

Back

Both positron emission and K-capture decrease the number of protons and increase the number of neutrons.
