Explain the trend in reactivity in group 7
WebSep 14, 2024 · Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic ... WebThe halogens are non-metals and when non-metals react with metals, they GAIN the electrons that the metals lose. As you move down group 7, the atomic radius get bigger (more protons, more electrons, more shells) and so the negatively charged electrons in the outer shell move further away from the positively charged nucleus.

WebAs you look at the trend in reactivity of group 7, the reactivity of halogens decreases so fluorine is the most reactive halogen and astatine is the least reactive halogen. Halogens … WebMar 14, 2024 · The ALFF of the left amygdala showed a trend interactive effect with group on the RT for anger (F 3,60 = 3.58, p = 0.018), however, it did not survive the multiple comparison correction (p FDR = 0.09). ALFF and RT were found to be moderately positively correlated for women on A-OC (r 14 = 0.50; Figure 2). The higher the ALFF in the left ...
WebThe elements in group 7 are called the halogens. Group 7 is on the right-hand side of the periodic table, next to group 0 The halogens show trends in their physical and chemical properties . 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.
Web4 rows · The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the ... WebFig. 1 (a) indicates the removal rates of COD in three continuous flow reactors with different Fe 0 dosages. With the increasing amount of Fe 0 from 0 to 30 mg/L, the COD removal rate of all three reactors showed a gradually increasing trend, and the AC-MFC reached the highest value (84.62 %), which increased by 9.72 % compared with that without Fe 0 …
WebThe electronegativity is the tendency of an atom to attract electrons towards itself in a covalent bond. The electronegativity of the halogens decreases down the group as the radius of each atom increases due to more shells. This means there is less attraction between the positive nucleus and the outer electrons as you go down the group.
