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...

PAX Prep NLN Verbal Comprehension Passages The way Things Work It was the ancient Greeks who first had the idea that everything is made up of elements. They conjured up just four of them-earth, fire, wind and water. As it turned out, the idea was right but the elements were wrong. Modern elements are less evocative but more numerous. They make up just over one hundred basic substances. Some are commonplace, like hydrogen, oxygen, iron and carbon; others are rare and precious, such as mercu...
