Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
Synthetic elements can be highly reactive due to their unstable nature and tendency to decay into more stable forms through radioactive decay or by forming compounds with other elements. Some synthetic elements have very short half-lives, making them extremely reactive in the short time they exist.
Highly reactive elements are often stored in inert environments, such as gases like argon or oils, to prevent them from reacting with other substances. Additionally, they may be stored in a form that minimizes their exposure to air and moisture, which could trigger a reaction.
The highly reactive non-metals are in the halogen group. They just need one more electron to fill the octet. Therefore they are highly reactive. For example fluorine and chlorine. And the highly reactive metals are placed in the first group (alkali metals). For example Sodium and potassium.
Fluorine is a highly reactive gaseous nonmetal element. It is the most reactive nonmetal on the periodic table and readily forms compounds with other elements.
Potassium is highly reactive, especially with water and air. It reacts vigorously with water to produce hydrogen gas and can ignite spontaneously in air.
Yes, sodium is a very reactive metal. It is highly reactive with water, oxygen, and other elements, which can lead to spontaneous reactions and even fires if not handled properly.
The group 18 elements are the noble gases, which are extremely inert. Some of them, heavier than argon, do form highly reactive compounds principally with fluorine.
To keep highly reactive elements from reacting, they are often stored in inert gases such as argon or mineral oil. This helps prevent them from coming into contact with oxygen or water, which could lead to unwanted chemical reactions. Storage in a controlled environment can help maintain the stability of these elements.
There are many reactive elements. They show up more on the upper left of the Periodic Table. Some of these are plutonium, uranium, Mercury and lead.
Not all elements with one valence electron are highly combustible, but some are. Elements like lithium (Li) and potassium (K) with one valence electron can be highly reactive and flammable. However, elements like helium (He) and neon (Ne) with one valence electron are inert and not combustible.
Fluorine is highly reactive and corrosive, which can easily react with many materials, including metals. Teflon is a highly inert and non-reactive material, making it suitable for storing and handling fluorine safely without reacting with the container.
