Bismuth (Bi)
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
Elements in the same group as cesium
Group-1 and 2 have metallic properties. They possess same properties.
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
A pair of elements in the same group are more likely to have similar properties. This is why groups are also called families. In the main group elements, groups 1,2, 13-18, the elements in a group have the same numbers of valence electrons in their outermost energy levels. This accounts for the fact that they behave in a similar matter in chemical reactions.
Group 1 or alkali metals are the most metallic elements.

most metals are metallic in a way. the periodic table consists of 3 different types of elements metals, non metals and metalloids the most metallic are the metals because they posses the most metal like properties.
Elements in the same group as cesium
The metals outnumber the non-metals by a good margin.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
Groups 3-12 have elements with the most diverse set of properties in the periodic table. They are transition elements.
Metallic character increases as one transitions down and right through the periodic table. By definition, francium (Fr) would be the most metallic, but only extremely small amounts of it exist at any given time, thereby rendering caesium (Cs) as the most metallic element.
In group 1 the first column on the left
All metals are highly reactive because of their properties. As you move left on a period while moving down you move close to Francium (most-metallic). Since group 1 is the most farthest left group, it is the most metallic, therefore the most reactive.
Group-1 and 2 have metallic properties. They possess same properties.
Francium is the most metallic element. :)
