PS-3 Periodicity. The
periodic table presents a pattern of chemical and physical properties of the
elements based on the element’s location on the periodic table. These properties
are based on the electronic structure of the atoms and nuclear charge.
TS-3.1 History of the periodic
table- A pattern of physical and chemical properties with the elements provides
the basis for the periodic table
3.1.1 Explain how the
first periodic table organized elements by mass and physical/chemical properties
to predict the existence of unknown elements (Mendeleev)
3.1.2 Describe how the modern periodic law was developed using atomic number (Moseley)
TS-3.2 Modern periodic table
arrangement- The periodic table contains groups of elements that share common
properties and electronic structures
3.2.1 Describe how elements are classified as metals, nonmetals & metalloids based on properties and their position on the periodic table.
Key Terms:
conductivity (electrical & thermal), malleable, ductile, shiny, valence
electrons
3.2.2 Identify periods & families on the periodic table by name, common properties and electron structure
Key Terms:
Lewis-dot structure (electron-dot structure)
TS-3.3 Explain how the following
periodic table trends in properties can be inferred from the electron structure,
nuclear charge and the effect of shielding by core electrons.
3.3.1 Describe the
trends for atomic radius
3.3.2 Describe the
trends for ionization energy
3.3.3 Describe the trends for electronegativity
Key Terms:
Effective nuclear charge
3.3.6 Describe the
family trends for reactivity of metals and nonmetals
