Chemistry Study Guide - Atomic structure and the Periodic Table 2010
Standards
3. Each of the more than 100 elements of matter has distinct properties and a distinct atomic structure. All
forms of matter are composed of one or more of the elements. As a basis for understanding this concept:
a. What is the structure of the atom and how are protons, neutrons, and electrons arranged
b. How can you use the periodic table to identify elements in simple compounds.
7. The organization of the periodic table is based on the properties of the elements and reflects the structure
of atoms. As a basis for understanding this concept:
a. Identify regions of the periodic table that correspond to metals, nonmetals, and inert gases.
b. Be able to illustrate that each element has a specific number of protons in the nucleus (the atomic
number) and each isotope of the element has a different but specific number of neutrons in the
nucleus.
c. Give examples how elements can be classified by their properties, including their melting
temperature, density, hardness, and thermal and electrical conductivity.
