An element's (or isotope's) atomic number tells how many protons are in its atoms.

An element's (or isotope's) mass number tells how many protons and neutrons in its atoms.

1. Uranium (U) has an atomic number of 92. How many neutrons are in the radioisotope U-235 (mass number 235)?

2. How many neutrons are in the isotope U-238?143

Non-Renewable Fuels – Nuclear

Radiation: any process in which energy is emitted by one body and is absorbed by another.

1. Ionizing Radiation – nuclear, x-ray, cosmic radiationChemical changes that damage biological tissues and structures

2. Non-Ionizing RadiationElectromagnetic, light, thermal radiation

Non-Renewable Fuels – NuclearNuclear Fuel Cycle

• Front End: preparing the fuel1. Exploration2. Mining and Milling3. Conversion4. Enrichment 5. Fabrication

• Service Period: using fuel in reactor Electricity, Medicine, Food and Agriculture, Military

• Back End: safely manage, contain, reprocess/dispose of spent fuel

• You will draw this pie chart in your notebook.

• The %s shown in chart are drawn exactly that % of a circle.

• 1 circle = 360 degrees.

Topic 1 Energy Sources – Fuels 1. Calculate angles

Circle = 360 degreesa. Oil = .42 x 360 = b. NG = .22 x 360 = c. Coal = .24 x 360 = d. Nuclear = .06 x 360 = e. Renew. = .07 x 360 =

2. Make sure all angles add up to 360 degrees.

~151~79

~86~22~25

We are 3 degrees over. Take 1 degree from 3 angles above

If correct:7. Darken lines and label

Oil – 41%NG – 22%

Coal – 24%

Renewables 7%

Nuclear 6%

BEWARE when using Pie Charts:1. Avoid using Pie Charts

when > 6 or 7 components. There are 5 in our example.

2. If %s are similar, it’s difficult to tell the difference between slices.
