CHEM1331 Chapter 2 (Atomic Structure and Periodicity) Q&A/CHEM1331 Chapter 2 (Atomic Structure and Periodicity) Q&A

Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energy...

Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines. In the second part of your initial post, we will be practicing naming ionic and covalent compounds as well as polyatomic ions. To begin, give the chemical formula for each of the following: A covalent comp...
