Answer: Cesium is the most reactive element since it is the second from the bottom of this group, has six electron shells, and exhibits the characteristics of a reactive atom.
The reactivity series is used to determine an element’s reactivity. Let’s start with the most reactive element and the reactivity series.
Reactivity series:
The activity series, sometimes known as the reactivity series, is a list of metals arranged in descending order of their activities. Because they are easily oxidized, the metals near the top of the reactivity range are powerful reducing agents. These metals discolor and corrode quickly.
The reactivity series data can be used to determine if a metal can displace another in a single displacement reaction.
It can also be used to determine metal reactivity in the presence of water and acids.
The ability of metals to donate electrons decreases as they progress through the activity series, which is an essential property.
The most reactive substance – Alkali metals are the most reactive element group (situated far apart from intermediate metals and noble gasses). Cesium is the most reactive element since it is the second from the bottom of this group, has six electron shells, and exhibits the characteristics of a reactive atom.
Fluorine is a noteworthy chemical element for many reasons, not the least of which is its unusual reactivity. In fact, it’s an element of extremes with a wide range of uses, and it could surprise us in the future.
Fluorine (atomic symbol: F) is the lightest member of the halogen group, commonly known as group 17 in the Periodic System of Elements, and the 13th most prevalent element in the earth’s crust.
Fluorine is a diatomic gas with a yellowish hue under normal conditions. It has a distinct odor that is distinct from the other halogens, chlorine (Cl), bromine (Br), and iodine (I).
Fluorine is the most electronegative element, which means that when it is connected to another element, it draws electron density towards its own core. Fluorine’s unique feature has not only made it the anchor point of the well-known Pauling electronegativity scale, but it has also changed the reactivity and properties of fluorine-containing compounds and materials as compared to non-fluorinated ones.
