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.
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.
Which is heavier lithium or potassium?
K is heavier than Li.
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.
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
What is more stable K or Kr?
Kr (krypton) is more stable than K (potassium) due to its full valence shell of electrons, which provides greater stability. Potassium is a highly reactive metal that readily loses its single valence electron, making it more chemically reactive and less stable than krypton, which is a noble gas with a full valence shell.
