6.1 Ionization of Atoms.
Atoms for positively charged ions when they lose electrons and negatively charged ions when they gain
Ionic bonds are formed by the strong attractive forces betw

Chapter 5 Nuclear Chemistry.
5.1 Natural Radioactivity.
An alpha particle has 2 protons and 2 neutrons. And it is identical to He nucleus with a charge of 2+
A beta particle is a high energy electron, with a charge of -1, formed when a neutron is changed
Chapter 3 notes
3.1 Classification of Matter.
2 forms of matter: Pure Substances and Mixtures.
Pure Substances can be either elements (composed of atoms) or compounds ( made up of elements).
Mixtures can be Homogenous (Composition is uniform throughout) o
Chapter 4. Atoms.
Pure substances from which all other things are built.
Cannot be chemically broken down into simpler substances
118 elements are known at this time.
An atom is the smallest unit of an element that exhibits the chemical prope

How many miles do you live from campus?
What type of variable is being collected? Continuous Qualitative.
A pattern I see in the data is that the majority of the class lives roughly 15 miles away from the Hamilton
campus. I think this is a symmetrical gra
