Activity 1.1: Penny Isotopes
Conducted February 19, 2015 to February 26, 2015
By Aliyah J. and Lydia M.
Pennies are made up of a combination of both zinc and copper. Not all pennies are
similar. Each penny has a different mass because they ar
Diatomic molecules and Activity Series
Diatomic molecules are elements that form two atom molecules in their natural
form at STP. Remember the phrase BrINClHOF (Br2, I2, N2, CL2, H2, O2, F2)
Write sulfur as S8 in chemical reactions.

Building Molecular Models
1) The basic way to find the electron is by using the octet rule. Depending on the
formula, I may make lone pairs or shared electrons alone, so the resulting
molecule/compound has an
Simple Nuclear Reactions Assignment
The presence of gamma rays doesnt affect how a nuclear
equation of alpha or beta decay is balanced because gamma
rays doesn't have an atomic number or mass number,
therefore it wouldn'
Vocabulary: Element Builder
Atom the basic unit of matter.
An atom is the smallest particle of an element that still
has all the properties of the element.
Atoms are made up of smaller particles called protons,
neutrons, and electrons. The
Predicting the Reactivity of Elements
Metals have been studied and utilized for a very long time, and we know a great deal
about their reactivity. In general, the reactivity of a metal is related to its ionization
energy. This is because metals tend to lo
