Trends down group 7
WebDec 21, 2024 · The boiling point trend explained Down group 7, the halogen boiling point increases because: • All the halogen molecules are two-atom covalent molecules. • There … WebThe more electrons there are in a molecule, the greater the instantaneous dipole-induced dipole forces; Therefore, the larger the molecule the stronger the London dispersion forces between molecules; This is why as you go down the group, it gets more difficult to separate the molecules and the melting and boiling points increase; As it gets more difficult to …

WebWhen a halogen atom reacts it will usually gain an electron, to form a 1- ion (X + e- → X-) The oxidation number has decreased from 0 to -1, therefore reduction has occurred. Therefore … WebIn Group 7, the reactivity of the elements decreases going down the group. AQA Combined science: Synergy. 4.5 Building blocks for understanding. 4.5.1 The periodic table. 4.5.1.5 Group 7. 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.
WebExplaining trends in reactivity. The reactivity of Group 7 elements decreases down the group. Non-metal atoms gain electrons when they react with metals. When a halogen atom reacts, it gains one electron into their highest occupied energy level (outer shell) to form a singly negative charged ion.
