Concept explainers
Interpretation: A list of elements named after a place needs to be determined.
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 3RQ
The name of elements: Americium, Germanium, Polonium, Francium, Californium
Explanation of Solution
A substance which is made from one type of atom is called element. Chemical elements may be considered as a basic chemical structure blocks of matter. The chemical elements are essential in our daily lives and the most important element is carbon. The elements americium, germanium, polonium, francium, californium, are seem like named after a place.
An element is described by the number of protons in the nuclei of its atoms.
