No, none of them. They do not combust -- they react with water.

they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
Yes, alkali metals will react with anything to get rid of that one valence electron, which makes them highly reactive.
Yes, the stability of noble gas elements other than helium is due to their having eight valence electrons. This electron configuration, known as an octet, gives them a full outer energy level, making them highly stable and less likely to form chemical bonds with other elements.
alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.
The "valence shell" of hydrogen contains only one electron. (This configuration is indicated as 1s1). Therefore, when it looses that electron, it is only a lone proton. This is highly important in acid/base reactions. Hydrogen, H, (and helium, He) does not follow the "octet rule" when forming bonds with other elements. Rather they both follow a special rule, sometimes called the "duet rule." While most elements want to have 8 valence electrons, H and He only want a total of 2.
Group 1 elements can easily lose its 1 valence electron and hence possess highly ionic character
They tell you how reactive the element is. If the atom has only one electron, then it is highly reactive. If the valence shell is full, then it will not react with other elements.

Highly reactive metals with one valence electron are known as Alkali metals.
Highly reactive metals with one valence electron are known as Alkali metals.

Alkali metals have only one valence electron and all of these elements are highly reactive. All of them are metals. Except lithium, other elements can be cut by a blade. They have a lesser density than water.

Yes. It is highly electronegative and only needs one valence electron so it is very voracious :)
Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.
