Electronic Structure and the
The electron configuration of the elements falls
into four blocks (s, p, d, f) in the periodic table.
Helium belongs to the s-subshell but is noted above
the p-subshell block on th
Matter and Energy - Vocabulary
Science that describes matter its properties,
the changes it undergoes, and the energy
changes that accompany those processes
Anything that has mass and occupies space.
The Foundations of Chemistry
A view from a molecular model perspective.

Law of Conservation of Matter
Law of Conservation of Matter
There is no detectable change in quantity of matter
Attractive forces that hold atoms together in
compounds are called chemical bonds.
The electrons involved in bonding are usually
those in the outermost (valence) shell.
Chemical bonds are

Chapter 6: Energy
6.2: Forms of Energy
Energy: the ability to do work; a property to classify a system.
System: a set of independent or interacting entities that form an integrated whole
Work: an object (mass) moved across a distance (physics definition)
5.2: Physical Properties
As temperature decreases, viscosity increases.
A physical change does not change the structure of the molecule from start to finish.
Chemical Changes: involve one set of molecules undergoing conversion to a second set. The

Intro to Gases
Breathing is an involuntary action; we take 12-60 breaths per minute.
There is a distinct variation of how electrons are shared between atoms.
Ionic: there is a complete transfer of electrons, usually from a metal to a nonmetal. > ca. 1.9
Polar covalent bond: a bond or sharing of electrons in which one constituent atom has
