Chapter 5

Upon completion of chapter 5, Advanced  and College Prep Chemistry students students will be able to:

Describe the modern periodic table.

Explain how the periodic law can be used to predict the physical and chemical properties of elements.

 Describe how the elements belonging to a group of the periodic table are interrelated in terms of atomic number

Describe the relationship between electrons in sublevels and the length of each period of the periodic table.

Locate and name the four blocks of the periodic table. Explain the reasons for these names.

Discuss the relationship between group configurations and group numbers.

Describe the locations in the periodic table and the general properties of the alkali

metals, the alkaline-earth metals, the halogens, and the noble gases.

Define atomic and ionic radii, ionization energy, electron affinity, and electronegativity.

Compare the periodic trends of atomic radii, ionization energy, and electronegativity, and state the reasons for these variations.

 Define valence electrons, and state how many are present in atoms of each main-group element.

 Compare the atomic radii, ionization energies, and electronegativities of the d-block elements with those of the main-group elements.
