What do alkali metals have in common?

Answer 1

They are all soft, highly reactive metals with low melting points.

They react vigorously or violently with water, producing hydrogen gas and the corresponding hydroxide.

They form 1+ ions and their compounds are water soluble.

Answer 2

As all of the Alkali Metals are in the same group, they naturally all share some characteristics. The main characteristic from a chemist's point of view would be that they are all highly reactive in contact with water. The main characteristic from a physicist's point of view would be that they all have 1 electron in the outer shell of their atoms.

Answer 3

Alkali metals are all highly reactive and readily lose their outermost electron to form 1+ ions. They are soft metals with low melting and boiling points and have similar chemical properties such as forming strong bases when reacting with water.

Answer 4

They all float, they all hiss, they turn water purple or blue and they have to be cut with a scalpal.

Answer 5

They all have one valence electron (one electron in the outermost shell of the atom).

Answer 6

They all react with water.

Answer 7

They are very reactive.
