Honors Chemistry

Chapter 5 Study Guide

Can you:

· Explain how Mendeleev organized his periodic table, and how it is different from the modern periodic table?

· Define period and chemical group or family?

· Explain why the term “periodic” is used for the arrangement of elements in the periodic table?

· List the properties of metals and non-metals?

· Identify the location on the periodic table and list elements from each of the following: Alkali metals, halogens, inert gases (noble gases), transition metals?

· Identify elements that fall within the s-block, p-block, d-block and f-block on the periodic table?

· Give the number of electrons in each energy level, the electron configuration and the number of valence electrons, for an atom using an its position on the periodic table?

· Explain how we know that the inert gases must have low potential energy?

· Explain why atoms close to having a full valence shell, or energy level, will gain or lose electrons so that they have a full valence shell?

· Explain why elements in the same group or family should have similar physical and chemical properties?

· Predict the electric charge on ions formed from elements in groups 1-3 and groups 15-17?

· Define ionization energy, electron affinity and atomic radius?

· Explain what is meant by an atom’s second or third ionization energy?

· List the factors that affect ionization energy and electron affinity, in order of priority (i.e. in order of which has the most effect)?

· List the factors that affect atomic radius, in order of priority?

· Given a list of elements, place them in order by their ionization energies, electron affinities or atomic radii, and explain why you have placed them in this order?

· Use mass and mole quantities in chemical reactions (mole problems)?
