Why do elements in the same group of the periodic table have similar chemical properties?Elements in the same group of the periodic table have the same number of protonsElements in the same group of the periodic table are all the same type of element (metal, non-metal etc.)Elements in the same group of the periodic table have the same number of electrons in their outer shellElements in the same group of the periodic table have different numbers of electrons in their outer shellQuestion 11 of 22 Loading... 12. How many electrons in a silicon ion?18410n/a (Silicon atoms have 4 electrons in the outer shell, so do not form ions)Question 12 of 22 Loading... 13. When are ions attracted to each other?When the ions are oppositely chargedWhen the ions are the same sizeWhen the ions are very smallWhen the ions have the same chargeQuestion 13 of 22 Loading... 14. Explain, in terms of structure and bonding, why magnesium oxide has a higher melting point than sodium chloride Sodium chloride is a simple molecular substance so there are only weak intermolecular forces which require little energy to breakNaCl and MgO both have a giant ionic structure with strong electrostatic forces between oppositely charged ions. The Ions in MgO have a charge of 2 and -2, but in NaCl the charges are 1 and -1. So the bonds in MgO require more energy to breakMg²⁺ and O²⁻ ions are larger than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Magnesium and oxygen are more reactive elementsQuestion 14 of 22 Loading... 15.
