Concept explainers

Actinides
The elements in which the extra electron tends to enter the 5f-orbitals of (n–2)th main shell are considered 5f-block elements. They are also named actinides. Actinides include 15 elements, from atomic number 89 to 103.

Chapter 7, Problem 7.6PAE
Interpretation Introduction

Interpretation:

Explain why the polarity of biomaterials is important.

Concept Introduction:

Water is a polar molecule having slightly positive charged hydrogen atoms and a slightly negative charged oxygen atom. Water's polarity allows it to dissolve other polar substances very easily. Water is the most common molecule in the human body.
