TLW (I can)
 I can identify the location, relative mass, and charge for electrons, protons, and neutrons. (C4.8A)
 I can describe the atom as mostly empty space with an extremely small, dense nucleus consisting of the protons and
neutrons and an electron cloud surrounding the nucleus. (C4.8B)
 I can recognize that protons repel each other and that a strong force needs to be present to keep the nucleus
intact. (C4.8C)
 I can give the number of electrons and protons present if the fluoride ion has a -1 charge. (C4.8D)
 I can write the complete electron configuration of elements in the first four rows of the periodic table. (C4.8e)
 I can write kernel structures for main group elements. (C4.8f)
 I can predict oxidation states and bonding capacity for main group elements using their electron structure.
(C4.8g)
 I can describe the shape and orientation of s and p orbitals. (4.8h)
 I can describe the fact that the electron location cannot be exactly determined at any given time. (C4.8i)
 I can identify elements with similar chemical and physical properties using the periodic table. (C4.9A)
 I can identify metals, non-metals, and metalloids using the periodic table. (C4.9b)
 I can predict general trends in atomic radius, first ionization energy, and electronegativity of the elements using
the periodic table. (4.9c)
 I can list the number of protons, neutrons, and electrons for any given ion or isotope. (C4.10A)
 I can recognize that an element always contains the same number of protons. (C4.10B)
 I can calculate the average atomic mass of an element given the percent abundance and mass of the individual
isotopes. (C4.10c)


I can predict which isotope will have the greatest abundance given the possible isotopes for an element and the
average atomic mass in the periodic table. (C4.10d)
I can write the symbol for an isotope, XZA, where Z is the atomic number, A is the mass number, and X is the
symbol for the element. (C4.10e)

Enduring Understanding(s):






An element is determined by the number of protons in its nucleus.
Elements consist of atoms.
Isotopes are atoms of the same element with a different number of neutrons.
The periodic table categorizes elements based on their atomic structure.
Individual elements have an emission spectrum that is always the same and that can be used to identify
the element.
Essential Questions(s):





What are elements and how does the structure of atoms determine the classification and reactions of
elements?
What is the relationship between atoms, ions and isotopes?
What is the electron configuration of an element?
What trends are observed with the periodic table?
What information can be gathered from the periodic table?
