Potassium (K) is more reactive than lithium (Li) due to its lower ionization energy and larger atomic radius. As you move down the alkali metal group in the Periodic Table, the atoms have more electron shells, making it easier to lose the outermost electron. This increased distance from the nucleus reduces the effective nuclear charge experienced by the outer electron, leading to greater reactivity. Additionally, the larger size of potassium means it can more readily participate in chemical reactions.
What else can I help you with?
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Is Rb more reactive then Li k Na Cs?
Yes, rubidium (Rb) is more reactive than lithium (Li), potassium (K), sodium (Na), and cesium (Cs). In the alkali metal group, reactivity increases as you move down the periodic table due to the increasing atomic size and the decreasing ionization energy, which makes it easier for the atoms to lose their outermost electron. Thus, Rb, being below K and Na, is more reactive than all of them. However, cesium (Cs) is even more reactive than rubidium.
What is the most reactive among Li Na K Rb?
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).
What Group 1A elements is the most reactive cs Li K Na?
K
Is Ag more reactive than K?
Potassium (K) is more reactive than silver (Ag). Potassium is an alkali metal on the far left side of the periodic table, making it highly reactive with water and oxygen. Silver is a transition metal that is more stable and less reactive compared to alkali metals like potassium.
Is k or mg more reactive?
Potassium (K) is more reactive than magnesium (Mg) because potassium is a more reactive metal due to its lower position in the reactivity series. Potassium reacts more violently with water and air compared to magnesium.
Why k is more reactive than na?
Potassium (K) is more reactive than sodium (Na) because potassium has a lower ionization energy and a larger atomic radius compared to sodium. This makes it easier for potassium to lose an electron and form a positive ion, leading to greater reactivity.
Which is more reactive sodium or lithium or potassium?
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.
Is (K) more similar to (Li) or (Pb) why?
Potassium (K) is more similar to lithium (Li) than to lead (Pb) because both K and Li are alkali metals located in the same group (Group 1) of the periodic table. They share similar chemical properties, such as reactivity and the formation of +1 ions. In contrast, lead (Pb) is a heavier post-transition metal in Group 14, exhibiting different properties and behaviors. Thus, K's similarities in group characteristics align it more closely with Li.
Which is heavier lithium or potassium?
K is heavier than Li.
What element is more dense than water?
All of them except for Li, Na, K, and the ones that are gaseous at room temperature.
What element reacts with H2O to produce H2?
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
