Unit 2: Atoms & the Periodic Table Standards
SPS1. Obtain, evaluate, and communicate information from the Periodic Table to explain the relative properties of elements based on patterns of atomic structure.
a. Develop and use models to compare and contrast the structure of atoms, ions and isotopes. (Clarification statement: Properties include atomic number, atomic mass and the location and charge of subatomic particles.)
b. Analyze and interpret data to determine trends of the following:
• number of valence electrons
• types of ions formed by main group elements
• location and properties of metals, nonmetals, and metalloids
• phases at room temperature
c. Use the Periodic Table as a model to predict the above properties of main group elements.

Neutral Atoms, Isotopes, and Ions
Watch the following video for more information to compare and contrast atoms, isotopes, and ions.
The following Graphic Organizer explains how atoms compare based on the subatomic particles. You must understand the similarities and differences between neutral atoms, ions, and isotopes.
Neutral Atom: A neutral atom (of any element) has an equal number of protons and electrons. If you change the number of protons it will no longer be the same element. Protons identify the element, and are the same as the atomic number.
Molecule: A molecule is a chemical bond of two or more atoms of the same element. Ex: H2
Isotope: Atoms of the same element can have a different number of neutrons. Therefore, isotopes of the same element have a different relative atomic mass. The atomic mass identified on the Periodic Table is the average atomic mass of all the isotopes that exist for that element.
Ion: Atoms of an element may gain or lose electrons. This causes the total number of protons and electrons to be different (unequal). If an atom gains electrons, it becomes an ANION (a negative ion). If an atom loses electrons, it becomes a CATION (a positive ion). Ions are created by chemical means when an atom bonds with another atom.
