Trend in reactivity down group 7
WebThis page explores the trends in some atomic and physical properties of the Group 7 elements (the halogens) - fluorine, chlorine, bromine and iodine. You will find separate … WebThe trends in boiling points down group 7. You can see from the photographs above that the halogens at the top of the periodic table are gases, bromine in the middle is a liquid, and at the bottom is solid iodine. So as you go down group 7 the halogen boiling point increases. We can explain this.
Trend in reactivity down group 7
Did you know?
WebAs you go down group 7, reactivity of the halogens decreases because: The atomic mass of the halogens increases. They increase in electron shells; so the atoms are larger as you go down the group. Therefore, the attraction of the outer electron to the nucleus decreases as you go down group 7. WebGroup 7 elements are all non-metals and exist as diatomic molecules. In each molecule, two atoms of the element are held together by a single covalent bond. Adjacent diatomic molecules have weak London forces between them. Halogen atoms have 7 electrons in their outermost shell. The electron configuration of their outermost shell is always s2 p5.
WebGroup 7: Reactivity (GCSE Chemistry) Halogens – trend in reactivity. As you look at the trend in reactivity of group 7, the reactivity of halogens decreases so fluorine is the most … WebDown Group 7 we have seen that the atoms become larger so the outer electrons are further away and are therefore more shielded from the positive nucleus. Larger halogen actoms …
