Day 4 skills review

DAY 4, Terms to know:

Sections 2.3-2.6, 3.1 atomic number, mass number, isotope, average mass, isotopic natural abundance, periodic table, halogens, noble gasses, transition metals, energy, kinetic energy, thermal energy, potential energy, chemical energy, electrostatic energy, law of conservation of energy, joule

DAY 4, Specific outcomes and skills that may be tested on exam 1:

Sections 2.3-2.6, 3.1

• Be able to use elemental symbols to determine how many protons, neutrons, and electrons are present in an atom
• Given a specific number of protons, neutrons, and electrons, be able to give a complete elemental symbol including element, mass, and charge
• Given isotopes and their natural abundance, be able to calculate the average atomic mass
• Given an average atomic mass and two or three isotopes, be able to describe the isotopes relative abundances
• Be able to describe possible transformations from one form of energy to another
• Given a process that involve a transfer of energy, be able to describe to describe what forms of energy exist before and after the process

Complete these problems outside of class until you are confident you have learned the SKILLS in this section outlined on the study guide and we will review some of them next class period.  2.15  2.17  2.19  2.21  2.35  2.67  2.69  2.79  2.81
