Because Alkali metals are in the first group of the periodic table, they are classified as having only one valence electron. Recall that the ionization energy is the energy required to ionize a particular species. As you increase the amount of electrons in the valence, more energy needs to be added to remove more electrons. For example, if there were two balls on your side of the court, it would take more energy to lug those two over as opposed to just throwing one. So ionizing sodium would be much easier than ionizing an atom like carbon which has 4 valence electrons. The net energy gain/loss from ionization comes down to two important factors: 1) does it have a closed configuration; and 2) is it thermodynamically stable? Generally, highly reactive substances are not stable because they can form molecules with very powerful bond strengths. If you have a very stable molecule, breaking it apart would require a lot of energy -- the bond-dissociation energy. Long story short, it is energetically favorable to have alkali metals bonded.

What are the group of soft silvery reactive metals known as?
alkali metals
Are alkali metals considered to be very reactive or very unreactive?

The Family of what is the most reactive group of metals in the periodic table?
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.

Which family of elements are the most reactive metals?
Alkali metals in the first group compose the most reactive family of metals.
