Well, several are, and from left to right. Alkali metals Alkaline earth metals. Transition metals. Metaloids. Nonmetals. Halogens. Nobel gasses.
Alkali, alkaline earth metals, and nonmetals.
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).
I think alkali is the most reactive one.
The alkali metals, the alkaline earth metals, the transition metals, metalloids, nonmetals, including the halogens and the Nobel gasses.A simplified list including general groups and families of elements.
Metals - especailly alkali and alkaline earths, and halogens.
The alkali group of metals is the most active.
The basic famillies are - Group 1 the alkali metals. Group 2 the alkali earth metals Group 7 the halogens Group 0 or 8 (depending on your periodic table) are the noble gases.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
alkali metals
Alkali metals , alkaline earth metals and halogens are most important ionic compound former .
