IONIC COMPOUNDS In this lesson, you will be exploring ionic bonding. You have encountered many examples of molecules containing Ionic bonds including table salt and sodium fluoride which is found in toothpaste. We will see in this lesson how ionic compounds are formed and how the formation of these compounds leads to the properties we observe. Which of the following would be considered an Ionic Compound? A. CH4 B. LiCl C. N2O4 D. SO In general, an ionic bond forms between atoms classifi...

In the human body, which of the following body parts are in a superior position to the lungs? - CORRECT ANSWER-Trachea and brain The part of the arm that is most distal to the shoulder of the human body - CORRECT ANSWER-The thumb is farthest away from the shoulder Which terms add clarity to anatomical posit...

CHEM120 Week 5 Concepts: Redox and Organic Chemistry – Download For Revision And Score An A+ OXIDATION-REDUCTION Reduction and oxidation are intertwined concepts that are important to understand ing some of the most important chemical reactions in the human body. In this lesson, we will explore the relationship between these terms and the how to identify what chemicals in a reduction/oxidation reaction (redox reaction) are playing which parts. 1. Redox reactions involve a transfer of: ▪ Nucl...

atom is the basic unit of matter. They are also known as elements number of protons in an atom determines its identity (which element it is). atomic number mass number is determined by adding the number of protons and the number of neutrons. charge of an atom is determined by the numbers of protons and electrons. Isotopes atoms of the same element that have different numbers of neutrons and, therefore, different masses. Electron negative charge Pro...
