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. ... Unlike the group 1 metals, reactivity decreases as you go down the halogens. This means that fluorine, at the top of the group, is the most reactive. ... WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the reactivity of the alkali metals and halogens increases or decreases, put a pin in the middle of the periodic table and spin it anti-clockwise.

WebFor group 1 Alkali metals- this means that the lower down the group the less energy needed to remove an electron so the easier it is to form positive ions/ easier to react. Now what about group 7 - halogens. These atoms will want to gain an electron to form a negative ion with a full outer shell. WebAs we go down a group the reactivity of non-metals decrease. This is because : The number of valence shells increases. The force with which the nucleus holds the electrons decreases. ... As you go down group 7, the atomic radius increases and it becomes more difficult to attract another electron. What is the reactivity of Group 2? 1.3. WebAs with group 1 and 2, the trends in properties and GENERAL reactivity in group 7 can be explained by their electronic configuration: The reason that melting and boiling points increase down the group is because the intermolecular forces between the halogen molecules (e.g. F 2, Cl 2, Br 2) get stronger down the group. painful itchy rash on back of neck
