Concepts to know:
 Know how to find the atomic mass, atomic number, element name and the element
symbol of an element when looking at a Periodic Table of Elements.
 Know how to find the number of protons, electrons, atomic mass and the number of
neutrons for an element.
 Know how to place electrons in their correct orbit.
 Know the names of these orbits.
 Know how to identify what elements and how many of each there are when given a
formula.
 Know the difference between metals, nonmetals and metalloids.
 Know the difference between the different states of matter.
 Know the difference between ionic and covalent bonding.
 Know the first 20 elements, their symbols and their atomic number.
 Know the basics of the periodic table.
What to study for the test?
 The two biggest things to study are the notes and the readings. Pay special attention to
the chapter reviews, they are a review of the readings.
 Also look over any labs and activities that we have done. I try to pull questions from
them as well.
 Use the quizzes as a study guide.
 Ask questions if you do not understand a concept.
