State Standards

Grade Eight
Periodic Table

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. Students know how to identify regions corresponding to metals, nonmetals, and inert gases.

b. Students know 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.

Grades Nine Through Twelve
Physics: Electric and Magnetic Phenomena

5. Electric and magnetic phenomena are related and have many practical applications.

As a basis for understanding this concept:

e. Students know charged particles are sources of electric fields and are subject to the forces of the electric fields from other charges.

f. Students know magnetic materials and electric currents (moving electric charges) are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources.

g. Students know how to determine the direction of a magnetic field produced by a current flowing in a straight wire or in a coil.

h. Students know changing magnetic fields produce electric fields, thereby inducing currents in nearby conductors.

Grades Nine Through Twelve
Chemistry Atomic and Molecular Structure

1. The periodic table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure. As a basis for understanding this concept:

a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass.

b. Students know how to use the periodic table to identify metals, semimetals, non-metals, and halogens.

c. Students know how to use the periodic table to identify alkali metals, alkaline earth metals and transition metals, trends in ionization energy, electronegativity, and the relative sizes of ions and atoms.
