WebThe most reactive metal element is francium. It is a highly unstable and radioactive element with the atomic number 87, and can only be produced in small qua... WebMETALS. The most reactive metals are those from Groups 1 and 2. They need to lose only one or two valence electrons to form positive ions with a noble gas configuration. NONMETALS. Nonmetals tend to attract additional valence electrons to form either ionic or covalent bonds. The most reactive nonmetals are the halogens, e.g., #"F"# and #"Cl"#.

What are the most reactive metals
WebGroup 2 (Alkaline Earth Metals) are the second most reactive metals. This is because this group contains only 2 valence electrons. So, it obeys the octet rule by losing both electrons. Generally, alkaline earth metals form ionic bonds. The exception is beryllium. Because of its small size, it has a relatively large electronegativity. This ... WebReactivity of Group 1 Elements. Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least ...
