Unit 3 Key Concepts

Identify the charge, relative mass, and position of the parts of the atom

Compare antimatter to normal matter

Use the Periodic Table to determine the number of protons, neutrons, electrons, energy levels, and valence electrons in an element

Given an isotope, determine if it is above or below the band of stability

Predict the type of decay an isotope is likely to produce

Determine the half life of an isotope from a half life curve

Given the amount of parent isotope remaining, determine the age of a sample

Explain the role of neutrons in the fission process

Explain the difference between sub-critical, critical, and super-critical masses

Describe how a fission bomb works

Use a binding energy curve to predict if a nuclear change would absorb or release energy

Evaluate the pros and cons of nuclear energy

determine if an element is a metal or a non-metal and compare the properties of each

Use a periodic table to determine electron configurations and to predict trends in atomic size and ionization energy

Draw an electron diagram for any element
