1.3 Define isotope and radioisotope and give examples
1.5 Identify examples of the medical and industrial use of nuclear energy.
Write 4 sentences for each in dot-point style:
Research the medical use of a diagnostic radioisotope (e.g. technetium-99 e.g. https://www.world-nuclear.org/information-library/non-power-nuclear-applications/radioisotopes-research/radioisotopes-in-medicine.aspx)
Research the industrial use of a radioisotope (e.g. a radio-tracer (e.g. Strontium-90) e.g. https://www.world-nuclear.org/information-library/non-power-nuclear-applications/radioisotopes-research/radioisotopes-in-industry.aspx#:~:text=Radioisotopes%20are%20used%20by%20manufacturers,and%20corrosion%20of%20process%20equipment.&text=Radiotracers%20are%20also%20used%20in,the%20extent%20of%20oil%20fields)

Put the heading Half-Life and under it create a table in your book with two columns of headings: Trial, # disks removed.
Take the disks and place them all facing the same way in the box.
Shake the box.
Remove, count and record the number of the disks that have turned over.
Repeat without replacing any disks.
2.1 Draw models to represent an atom, ion and isotope.

An atom's valence electrons:
are located closest to the nucleus
determine how stable it is
are related to the element's group in the periodic table
are in the atom's outer shell
The electron configuration of chlorine is 2.8.7. How many valence electrons does it have?

Where on the periodic table would you find the element with the electron configuration 2.8.2?
Period 2, Group 2
Period 2, Group 3
Period 3, Group 2
Period 3, Group 8
Elements in the same group of the periodic table have:
(Select all that apply)
the same number of valence electrons (except helium)
the same number of protons
similar properties
the same number of shells containing electrons
Select the statement that explains why the noble gases, in Group 18 of the periodic table, don't form ions.
They have full valence shells
They have the same number of neutrons
They have half-filled valence shells
They have empty valence shells
