what family of elements in the periodic table contains most reactive metals?
528223
The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.
639982
Alkaline Earth metals are very reactive because they readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.
631068
Rare Earth metals are a set of 17 chemical elements in the periodic table, specifically the fifteen lanthanoids plus scandium and yttrium. All lanthanoids are relatively soft and reactive metals. The rare earths metals are silver, silvery-white or gray metals which have a high luster, but tarnish readily in air.
1350402
All of the Group 18 elements of the periodic table. Nonmetals that are in group 17 in the periodic table and if an element has 7 valence electrons it either as to gain or share 1 electron. Very reactive.
694050
The most reactive kind of metallic element is an alkali metal of group 1 (e.g., sodium or potassium); this is because such an atom has only a single valence electron; during the formation of an ionic bond which provides the necessary ionization energy, this one valence electron is easily lost to form a positive ion ( ...

Alkali metals are known for being some of the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and often have an oxidation state of +1. These metals are characterized as being extremely soft and silvery in color.
392299
Transition metals. The transition elements are metals. They have high melting points and densities, and are strong and hard. They form coloured compounds and act as catalysts.

Group 1 - the alkali metals The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.
1461181
The most metallic element is francium. However, francium is a man-made element, except for one isotope, and all isotopes are so radioactive they almost instantly decay into another element. The natural element with the highest metallic character is cesium, which is found directly above francium on the periodic table.

Like the Group 1A elements, the alkaline earth metals are too reactive to be found in nature in their elemental form. The alkaline earth metals have two valence electrons in their highest-energy orbitals (ns2).
595944
Rubidium (Rb), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.
746664
Though both gold and platinum are among least reactive transition element metals, but still if we look at the reactivity series of metals we find that gold is more reactive than platinum.
358295
The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. Reactivity increases down the group.

There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements).

The Representative Elements are those elements within the first two families (Groups I and II on the far left) and the last six families or groups (on the right) of the Periodic Table. The Transition Metals are the elements in those Groups within the middle of the Table.
