Simple Molecules & Covalent Bonding quiz Loading... 1. Why is the boiling point of a larger molecule higher than that of a smaller molecule?Larger molecules have more attractions between them. These take less energy to overcome.Larger molecules have more attractions between them. These take more energy to overcome.Larger molecules have fewer attractions between them. These take less energy to overcome.Larger molecules have fewer attractions between them. These take more energy to overcome.Question 1 of 16 Loading... 2.

Give the definition of a covalent bondStrong electrostatic attraction between a shared pair of electrons and two nucleiStrong electrostatic attraction between a shared pair of electrons and a nucleusStrong electrostatic attraction between oppositely charged ionsStrong electrostatic attraction between a postive ion and a sea of delocalised positive ionsQuestion 8 of 16 Loading... 9. Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon has the same number of electrons and protons so it is unreactiveNeon has an even number of electrons so it doesn\'t need to form bondsNeon is a noble gasNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsQuestion 9 of 16 Loading... 10. How many electrons in the outer shell of group 5 elements?4658Question 10 of 16 Loading... 11. Describe the formation of a covalent bondThe sharing of a pair of electrons between two nucleiThe electrostatic attraction between positive metal ions and a sea of delocalised electronsThe transfer of electrons from one atom to anotherThe sharing of a single electron between two nucleiQuestion 11 of 16 Loading... 12. In the dot and cross diagram of the outer electrons showing the covalent bonding in a molecule of oxygen (O₂), how many electrons should be shown in areas 1, 2 and 3?There should be four electrons in area 1, four electrons in area 2, and four electrons in area 3There should be three electrons in area 1, two electrons in area 2, and three electrons in area 3There should be four electrons in area 1, two electrons in area 2, and four electrons in area 3There should be two electrons in area 1, six electrons in area 2, and two electrons in area 3Question 12 of 16 Loading... 13. Explain why carbon dioxide gas, CO₂, is a gas at room temperatureCarbon dioxide has a giant covalent structure with many strong covalent bonds which require a lot of energy to overcomeCarbon dioxide has a simple molecular structure with strong intermolecular forces that require a lot of energy to overcomeCarbon dioxide has a simple molecular structure with weak intermolecular forces that require little energy to overcomeCarbon dioxide has a giant covalent structure with many weak covalent bonds which require little energy to overcomeQuestion 13 of 16 Loading... 14.
