Define an atom.
Describe the five postulates of the Dalton’s Atomic Theory.
Use a drawing to illustrate a model of the atom. Describe particles, locations, masses, year
discovered, person who discovered them and experiment used.
Define and distinguish between these numbers:
Atomic number
Mass number (and relation to isotopes)
Atomic mass/Atomic weight
Give the symbols for alpha, beta, and gamma particles (include mass number and atomic number)
Balance nuclear equations involving alpha and beta decay
Differentiate between fusion and fission
Perform calculations with moles, particles, and grams
Perform calculations to determine atomic mass (using isotope data)
Describe the contributions of Democritus, Dalton, Rutherford, JJ Thomson, and Chadwick
