Department: ___Science_____________________
Teacher: ___Davis__________________
Topic / Theme: ____Electron Arrangement and Periodic Law_____________________________ ____
Essential Question:
How does the arrangement of electrons in
atoms determine the properties of elements
and the arrangement of the periodic table?
Key Questions: What are the physics theories that led to the
quantum mechanical model of the atom ? How do elements create
unique line spectra and how can those spectra can be used to identify
elements? How do you perform calculations relating wavelength,
frequency, speed of light, Planck's constant, and energy of a photon?
What are the four quantum numbers that determine the location and
energy of an electron? How do you draw an orbital box diagram
showing the ground state electron configuration for a given element?
How do you write the electron configuration of a given element? How
do you relate the electron configuration of an element to its location
on the periodic table? What are the shapes of s and p orbitals? How
do you write the noble gas configuration of a given element? How was
the periodic table developed? How do you determine the charge ion
an element will form according to its position on the periodic table?
How do you use the periodic table to identify metals and non-metals
and therefore some physical properties of those elements? How do
you use the Periodic Table to predict periodic trends including atomic
radii, ionic radii, ionization energy, and electronegativity of various
elements?
