WebI think I accidentally described why reactivity increases as you go from left to right across a row, just out of habit, since that question is so often associated with why reactivity … WebAnswer: For all groups in the periodoic table there is a trend, as you descend the group, the atomic tradius gets bigger. this means that the outer electrons are furtehr from the nucleus and are shielded from the nucleus to some degree by the inner electrons. Net effect- it is easier/ less energy...
WebFeb 8, 2024 · The reactivity of Group 7 elements decreases down the group. The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron. How does Group 1 … WebGroup 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 Therefore halogens will act as oxidising agents
