- Isotopes- basic notes, definitions and key points
- Chapter 3
- Be able to write out and interpret the nuclear (isotopic notation) symbol for an element and/or isotope and use this to determine the number of protons, neutrons and electrons for the element.
- Understand the basic composition of the modern model of the atom.
- Know the subatomic particles, their charges and relative masses in amu's.
- Distinguish between atoms, isotopes and ions.
- Distinguish between the average atomic mass and the mass number.
- Define and know some examples of common allotropes.
- Know that the average atomic mass on the periodic table is a “weighted” average of the elements naturally occurring isotopes.
- Given percent abundance data and atomic masses in amu’s you should be able to calculate the average atomic mass of an element.
- Know how isotopes of the same element are different from each other and be able to use examples to show why it is important to learn about them, ex: how are they used?
- Know that mass spectrometry is the technique that scientists use to determine the masses of elements, isotopes and molecules which has many applications in science and forensics. You should be able to interpret a simple spectrum from a mass spectrometer analysis.
- Have a basic understanding of how scientists are able to synthesize and create new elements.
