Essay about Atom and Nonpolar Covalent Bonds

Essay about Atom and Nonpolar Covalent Bonds Essay about Atom and Nonpolar Covalent Bonds 1. Carbon can engage in four covalent bonds. 2. Nonpolar covalent bonds polar covalent bonds ionic bonds 3. C N O H 4. Hydrogen bonds only form between atoms that are engaged in covalent bonds that are polar. 5. Electrons are shared equally in CH4 and unequally in NH3 6. Carbon, hydrogen, nitrogen, oxygen 7. Number of protons 8. The number of protons plus neutrons in the element 9. Some carbon atoms in nature have more neutrons. 10. 15 protons and 15 electrons 11. Outer-shell electrons of two atoms are shared so as to satisfactorily fill their respective orbitals 12. Each hydrogen atom has a partial positive charge; the nitrogen atom has a partial negative charge. 13. Nonpolar covalent bonds 14.One of the atoms sharing electrons is more electronegative than the other atom 15. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between charged atoms. 16. Silicon 17. Two 18. Almost empty; cations 19. Single, double, or triple 20. Carboxyl 21.Amino 22. Oils are nonpolar molecules that cannot interact with water molecules via hydrogen bonding. 23. Water has a high specific heat. 24. An acid. 25. Polar covalent bonds. 26. Electrons in H2 and O2 have relatively high P.E; electrons in H2O have relatively low P.E. 27. A decrease in potential energy from reactants to products is released as heat. 28. Potential energy 29. Energy is neither created nor destroyed 30. Sulfhydryl 31.Amino 32. The partial negative charge on oxygen would stick out less and be less able to participate in hydrogen bonding. 33. Oils are nonpolar molecules that cannot interact with water molecules via hydrogen bonding. 34. (13.7) 35. (7.59 Ãâ€" 10−4) 36. It would make the molecule more soluble
