Ions quiz Loading... 1. Which group of atoms has a full outer shell?Group 2, alkaline earth metalsGroup 0, the noble gasesGroup 7, the halogensGroup 1, the alkali metalsQuestion 1 of 22 Loading... 2. What holds ions together?Ions are held together by a strong electrostatic attraction between the similarly charged ionsIons are held together by a strong electrostatic attraction between the oppositely charged ionsIons are held together by a strong electrostatic attraction between the shared pair of electrons and their nucleiIons are held together by a strong magnetic attraction between the oppositely charged ionsQuestion 2 of 22 Loading... 3. 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 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.NaCl 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 breakMagnesium and oxygen are more reactive elementsQuestion 3 of 22 Loading... 4. 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 electronic configurationsame number of electrons in the outer shellSame number of electrons in the inner shellsame number of electron shellsQuestion 4 of 22 Loading... 5. Explain, in terms of electrons, why isotopes have the same chemical propertiesIsotopes have the same number of electronsIsotopes have different massesIsotopes are radioactiveIsotopes have the same number of protons but a different number of neutronsQuestion 5 of 22 Loading... 6. State the formula of the hydrogen ionH⁺H₃O⁻H₃O⁺H⁻Question 6 of 22 Loading... 7. Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon has an even number of electrons so it does not need to form bondsNeon has the same number of electrons and protons so it is unreactiveNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsNeon is a noble gasQuestion 7 of 22 Loading... 8.
