Hydrogen gas and the hydroxide of the particular group one element in question.
all will react
The Alkali metals (group 1) and the Alkali Earth metals (group 2) react violently with water. Lithium and magnesium show slow reactions in boiling water. Sodium and potassium reacts violently with flames with cool water. The elements in higher periods (strontium, barium etc.) react explosively.Elements in the 1st group react rapidly with cold water. The rate of reaction increases down the period. The elements in the 2nd group also reacts with hot water or steam.
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.
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.

Magnesium is highly reactive and will react with many things. It will react with elements of the Nitrogen group, the Oxygen group and the halogens. It will also react with acids, water etc.
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
Most of them do NOT react with water. Only fluorine and to some extend chlorine do. Actually the only good 'water reacting' group of elements is group 1: the alkali 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.

Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
The elements in group 1 combine easily with other elements to form compounds because they are trying to get rid of their extra electrons. That is why, for example, potassium will react strongly in water. Hope this helps.

The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
