WebThe halogens, group 7, are an important group of elements both chemically and socially. They are unusual in that they are coloured and diatomic. They also have an order of … 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. The number of electrons increase.

WebProperties of the group 7 elements As you go down the halogens, from fluorine to astatine, the elements become darker in colour and have a higher boiling point. Boiling point increases as you go down the group because the mass of each element increases and they have more electrons around their nuclei. list of struct in golangWebAug 21, 2024 · In each case, a halogen higher in the group can oxidize the ions of one lower down. For example, chlorine can oxidize bromide ions to bromine: (3) Cl 2 + 2 Br − → 2 Cl − + Br 2. The bromine forms an orange solution. As shown below, chlorine can also oxidize iodide ions to iodine: (4) Cl 2 + 2 I − → 2 Cl − + I 2. list of structurally deficient bridgesWebThe halogens, group 7, are an important group of elements both chemically and socially.
