Chapter 21, Problem 21.28SP

Interpretation Introduction

Interpretation:

Using the electro negativities of the early and late transition metals, explain why one type prefers to form oxides while the other forms sulfides.

Concept introduction:

• d- and p-block elements are generally found in nature as metal oxides and sulfides.
• s-block elements occur as chlorides, silicates and carbonates.
• Group 3B metals occur as phosphates and platinum group metals and gold are found in an uncombined form.

To classify:Why early transition metals form oxides while late transition metals form sulfides.
