Webfluorine and the least electronegative is iodine, so down group 7 the halogens become less electronegative. Down group 7 • Successive atoms have more occupied energy levels. • The distance between the nucleus and the pair of electrons in a covalent bond increases. • The attraction of the nucleus for these electrons decreases ... WebWith increasing atomic size of the halogens (going down the group) their electronegativity, and therefore oxidising power, decreases Group 7 Reactivity Reactivity When 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 greek consonants wsj crossword
