Legislative size is a trade off between efficiency and representation; the smaller the legislature, the more efficiently it can operate, but the larger the legislature, the better it can represent the political diversity of its constituents.
The most chemically reactive metals are the alkali metals. Francium is the most reactive of these and of all metal (although it is present on earth only in exceedingly small q â¦ uantities, due to its radioactivity). The most reactive element available in useful quantities in Flourine.
You will often find them bonding with metals and elements from Group One of the periodic table. The elements in the column on the left each have one electron that they like to donate. We've just told you how reactive the halogens are. Not all halogens react with the same intensity or enthusiasm. Fluorine is the most reactive and combines with most elements from around the periodic table.
