9 мар. 2016 г. · In Non-metals Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group.

Metals Period - reactivity decreases as you go from left to right across a period. Group - reactivity increases as you go down a group.

All group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron.

31 июл. 2018 г. · This is because the number of valence electrons increases, making it difficult to lose electrons. Moving further right in the period towards non ...

The larger the atom, the larger the separation between the nucleus and the electron, meaning it is easier to remove, and thus, the atom is more reactive.

The reactivity of non – metals increases from left to right in a period whereas reactivity decreases in a group as we go down the group.

9 янв. 2020 г. · Statement I: There is a high chemical reactivity of elements at extreme left and right of periodic table.

9 нояб. 2022 г. · There is also an increase in electron density which makes the atom more reactive. Hence, reactivity increases from moving across a period.

20 окт. 2021 г. · The reactivity of metals increases from right to left on the periodic table because of several factors, such as the number of valence electrons, atomic radius, ...
