Smaller, Smaller Larger, Larger Smaller, Larger Larger, Smaller Question 15 5 pts Moving top to bottom down a group, atomic radius__and ionization energy - Decreases, Increases Increases, Decreases Decreases, Decreases Increases, Increases Question 16 5 pts Which element would have the largest radius? Ca Na Mg Question 17 5 pts Which of the following is not a property of metals? Formation of negative ions Good conduction of heat Good conduction of electricity Malleable

Answer 1

14. Cations (positive ions) are Parent atoms. smaller than their due to increase in effective nuclear charge Anions (negative ions) are larger then their parent atoms It is due to increase in repulsion due to an extra electron. 15. Moving top to bottom down a group, atomic radius. increases and ionization energy decreases - Addition of extra shell down a group increases the atomic radius and decreases the lonization energy. 16. K will have the It is because it present on left largest radius is lower in the period in the group and 17 Formation of negative ions is not the property of metals. - Metals form positive ions (cations)
