group 1 (Alkali Metals)
1
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
1. alkaline metals 2. alkaline earths metals
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
reactivity of any element depends on its form.Ca reacts in its Ca+2 form and forms CaCo3 (Calcium carbonate)CaSo4(calcium sulphate) etc.
Group 1 elements are more reactive than that of group 2 elements.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
Sodium is more reactive then Magnesium as it is a group 1 element and magnesium is a group 2 element
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water

Beryllium is the least reactive in the group 2.
No that is group 2. Group 1 is called Alkali metals.
The difference between group 1 and group 2 metals is that group 1 metals have ONE valence electron and group 2 have TWO valence electrons. This makes a great difference in how they react chemically with other elements and compounds.
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
