The elements listed are Group 1 elements, the Alkali metals. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). Use the link below to check facts and learn more.
Alkali metals in the first group compose the most reactive family of metals.
Check out Sodium, Potassium, Phosphorus Magnesium too once you get it started.
Sodium is a very reactive chemical element.
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg
You think probable to aluminium.
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
The element lithium has the symbol Li.The element sodium has the symbol Na (from natrium in Latin and Νάτριο in Greek)The element potassium has the symbol K (from kalium, Latin).
Potassium is more reactive than lithium, which is more reactive than sodium. This trend is based on the alkali metal group's reactivity, with reactivity increasing as you move down the group due to the decreasing ionization energy and increasing atomic size.
Cesium is the most reactive Group 1A element because it has the lowest ionization energy and the largest atomic radius, making it more willing to donate its outermost electron in a chemical reaction compared to potassium, lithium, and sodium.
Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
i think the element will be lithium that's what i think
Sodium, potassium, and lithium are reactive metals that are kept in oil to prevent reaction with air or moisture. Among these, potassium is the most reactive, followed by sodium and then lithium. Keeping them in oil helps to maintain their reactivity for specific chemical reactions.
Sodium
Reactivity increase down the group.Ceasium is the most reactive.
Iron is the odd one out because it is a transition metal, while lithium, sodium, and potassium are alkali metals.
sodium and lithium are both group 1 elements (like potassium)
Lithium (Li) is the most reactive among Li, Na, K, and Rb due to its small atomic size and low ionization energy, making it easier for it to lose its outer electron and form compounds. Sodium (Na) would be next in reactivity, followed by potassium (K) and then rubidium (Rb).
