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...

Glycine Glycine is the most simple amino acid - its best to just memorize that this important amino acid has a functional group that only contains a hydrogen! Alanine Alanine has a really simple functional group (just a simple methyl group) that some of the other AA functional groups build on. You can remember the name because the alphabet builds on the letter A and other functional groups build on the simple Alanine R group. What about the other A amino acids? well Alanine has the shor...
