Chapter 22, Problem 5PS

Interpretation Introduction

Interpretation:

The physical and chemical properties of the transition metal elements should be identified.

Concept introduction:

The groups 3 to 12 on the periodic table (d-block of the periodic table) are called Transition metal elements. The lanthanide and actinide series are also considered as inner transition metals.

• Physical properties are those that can observe or measure.

  Physical properties of the elements are color, melting point, boiling point, mass, volume, density, length and shape.

• Chemical properties are those that describe how a substance reacts or change into a new substance and based on the reactivity, for example the substance reacts with acid, base, air, water and other chemicals.
