Elements in the second group have 2 outer shell electrons and are also v ery reacve. Elements in the rst group have one outer shell electron and are extremely reacve. The horizo ntal rows on the period ic table are called _ _ _ _ _ _ _ _. The verca l column s on the periodi c table are called _ _ _ _ _ _ _ _. The elemen ts in the far upper right corn er are classi ed as_ _ _ _ _ _ _. The elemen ts that touch the zigz ag line are class ied as _ _ _ _ _ _ _. Most of the eleme nts in the period ic table are class ied as _ _ _ _ _ _ _ _. Give two properes of nonmetals: _ _ _ _ _ _ 5. Give two properes of metals: _ _ _ _ _ _ 4. The three classes of elements are _ _ _ _ _ _ _ 3. The trends in ionisation energies across periods and down groups can be explained in terms of the atomic size, nuclear charge and the screening effect due to inner shell electrons.C4.1b explain how observed simple properties of Groups 1, 7 and 0 depend on the outer shell of electrons of the atoms and predict properties from given trends down the groups.C4 Predicting and identifying reactions and products.C2.3.2 explain how observed simple properties of Groups 1, 7 and 0 depend on the outer shell of electrons of the atoms and predict properties from given trends down the groups.C2.3 How do metals and non-metals combine to form compounds?.6.13 Explain the relative reactivity of the halogens in terms of electronic configurations.6.5 Explain this pattern in reactivity in terms of electronic configurations.5.1 Atomic structure and the periodic table.Explain how the observed simple properties of Group 7 depend on the outer shell of electrons of the atoms and predict properties from given trends down the group.Explain how the observed simple properties of Group 1 depend on the outer shell of electrons of the atoms and predict properties from given trends down the group.Students should be able to: explain how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms.
