ESSENTIAL QUESTION: How are elements arranged?
RELEVANCE: Why use a periodic table?
NGSSS: SC.912.P.8.3; SC.912.P.8.4; SC.912.P.8.5; MAFS.912.N-Q.1.1; LAFS.910.WHST.1
LEARNING OBJECTIVES: Students will be able to:
-Read and interpret a periodic table.
-Describe how the elements are arranged on the periodic table.
-Distinguish between the different families of elements and their properties.
BELL RINGER: Read the challenge. Highlight the section that explains which elements are the same and which are different on earth and on Chykogon.
VOCABULARY: atom, atomic number, electron, electron dot diagram, element, energy level, ion, isotope, mass number, neutron, nucleus, periodic table, proton, radioactive, valence electrons
HOME LEARNING: update notebook, complete vocabulary, study
AGENDA
WHOLE GROUP
For the bell ringer, students read the introduction to the activity and determined which sentence supplied information about the similarities between the Chykogen elements and those found on Earth.
Some students continued the grouping of the elements of the periodic table by family activity. Be sure to include your key.
Students also completed notes on the elements and the periodic table. They first completed the table below with the correct information.
Parts of the Atom
Particle Name Charge Location AMU
Proton
Neutron
Electron
Students then wrote note, including:
# protons = atomic number
# protons + # neutrons = atomic mass
Atomic mass - # protons = # neutrons
An atom has no charge, having the same number of protons and electrons (# protons = # electrons).
An ion is charged, having either more protons or electrons.
Finally, students were asked to define the following:
periodic law
alkali metals
alkaline earth metals
transition metals
metalloids
nonmetals
halogens
noble gases
