Valence bond theory - Study guides, Class notes & Summaries

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 energ...

Gen Chem 1 Final Exam Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is the principle behind the law of conservation of mass in a chemical reaction? The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products. How do you determine the number of valence electrons in an atom? The number of valence electrons can be determined by the group number of the eleme...
