WebReactivity trends of the alkali metals Experiment RSC Education Use this experiment to demonstrate the trend in reactivity down group 1 of the Periodic Table, exploring the physical and chemical properties of the alkali metals. WebThe 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. There are more electrons shielding the positively charged nucleus from the outer electron.

WebNov 18, 2024 · The decrease in the reactivity down Group 17 can be explained as follows. All halogens have seven valence electrons. Each halogen atom will gain one electron to achieve a stable octet electron arrangement. Hence, an ion with a charge of -1 is formed. When going down Group 17, the atomic size of halogens increases. WebNov 9, 2024 · Reactivity. The elements of the Periodic Table show various trends. These trends are broadly divided into two categories, i.e., physical properties and chemical properties. There are many observable patterns in elements’ physical and chemical properties as we move across a period or down in a group in the Periodic Table. bittrex automated maintenance navcoin
