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...

MetabolismAnabolism+catabolism. the chemical processes that occur within a living organism in order to maintain life. Enzymatic Reactions inside a living organism CarbonCarbon is an element with the atomic number 6, meaning it has four electrons in its outer shell. These electrons can form covalent bonds with carbon atoms or atoms of other elements. This allows a diversity of stable compounds to exist.
