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 sections below covering the trends in atomic radius, electronegativity, electron affinity, melting and boiling points, and solubility. There is also a section on the bond ... WebSo, ionization energy decreases down the group. As the ionisation energy decreases, it becomes easier to remove an electron from the outermost shell. So, an element from this group becomes a positive ion more easily and hence is ready to undergo a chemical reaction. Hence, down the group reactivity increases. Suggest Corrections.
Why does reactivity of halogens decrease down the group?
WebSep 2, 2024 · Volatility decreases down the group as the boiling points increase. As you go down group 7, the halogens become less reactive. This is because: Decreasing reactivity, - Atomic radius increases. - Nuclear charge increases, so the nuclear attraction on the outer electrons are stronger. WebHalogens Elements in group 7 of the periodic table. Halides An ion with a 1- charge formed when a Halogen atom gains an electron. Noble gases Elements in group 0 of the periodic table. Inert Not chemically reactive. Group 7 Elements • Also called the halogens. • As elements they form molecules that contain two atoms. • E.g. Cl2 is chlorine opening an organic grocery store

WebIf you have a Fannie Mae or Freddie Mac loan and your loan servicer learns that you've applied to your state's Homeowner Assistance Fund program, the servicer must suspend foreclosure activities for up to 60 days. (In early 2024, President Joe Biden signed the American Rescue Plan Act into law. WebAs you go down group 7, the atomic radius increases and it becomes more difficult to attract another electron. Why does group 7 get less reactive? Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron ... opening another credit card
