The reactions of Group 1 elements with Br2 are very vigorous. For example, Sodium it would go 2Na + Br2 = 2 NaBr.
1 (fully) and 4 (only partial) are decomposition reactions.
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
Group 1 Metals
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group 1 elements are more reactive than that of group 2 elements.
Violent oxidation reactions.

No, oxygen is not given off when group 1 elements react with water. Instead, these reactions typically result in the formation of hydroxide ions and hydrogen gas.
The group of elements in the periodic table known as the alkali metals is group 1, which includes lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically form ionic compounds in reactions.

44.0 grams Br2 ? 44.0 grams Br2 (1 mole Br2/159.8 grams)(6.022 X 10^23/1 mole Br2)(1 mole Br2 atoms/6.022 X 10^23) = 0.275 moles of Br2 atoms
Group 1 Metals
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
Group 1 elements have an oxidation number of +1.
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group IA or group 1 elements are known as alkali metals.
Group 1 elements are more reactive than that of group 2 elements.
