In the dot and cross diagram of the outer electrons showing the covalent bonding in a molecule of hydrogen (H₂), how many electrons should be shown in areas 1, 2 and 3?There should be zero electrons in areas 1 and 3, and two electrons in area 2There should be seven electrons in areas 1 and 3, and two electrons in area 2There should be seven electrons in areas 1 and 3, and four electrons in area 2There should be six electrons in areas 1 and 3, and two electrons in area 2Question 8 of 16 Loading... 9. Explain why nitrogen gas, N₂, is a gas at room temperatureNitrogen has a simple molecular structure with weak intermolecular forces that require little energy to overcomeNitrogen has a giant covalent structure with many weak covalent bonds which require little energy to overcomeNitrogen has a giant covalent structure with many strong covalent bonds which require a lot of energy to overcomeNitrogen has a simple molecular structure with strong intermolecular forces that require a lot of energy to overcomeQuestion 9 of 16 Loading... 10. On the Periodic Table what is the meaning of the word Period? What does that tell us about the electron configuration of the atom?Same number of electrons in the inner shellsame number of electron shellssame number of electrons in the outer shellSame electronic configurationQuestion 10 of 16 Loading... 11. What is special about the elements in group 0?They are all diatomicThey have the same number of electronsThey are all coloured gasesThey are very unreactive (because they have full outer electron shells)Question 11 of 16 Loading... 12.
