Yes, potassium is more reactive than rubidium. This is because potassium has a lower atomic number and smaller atomic radius compared to rubidium, making it easier for potassium to lose an electron and form a positive ion. This increased reactivity is also evident in the reactivity series, where potassium is placed above rubidium.
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.
Yes, rubidium has a higher melting point than potassium. Rubidium has a melting point of 39.3°C, while potassium has a melting point of 63.4°C.
The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.
potassium is more reactive because it has more outer shells of electrons than hydrogen. more outer shells means a weaker pull from the positive proton. this means it is easier to lose an electron with a weaker pull from the proton
I would expect cesium, element 55, to be more reactive than potassium. This is because cesium is further down the alkali metal group in the periodic table, making it more eager to lose an electron compared to potassium.
The atomic radius of potassium is greater than that of sodium. Therefore, the single valence electron that exists for all alkali metals is located farther from the nucleus for potassium than sodium. This results in less energy required to remove that valence electron from potassium than from sodium, leading to increased reactivity. Note that this trend continues as you move down Group I on the Periodic Table, meaning that Rubidium is more reactive than Potassium and Cesium is more reactive than Rubidium.
Rubidium is softer than potassium. This is because rubidium has larger atomic size and higher reactivity, which makes it more easily deformable when compared to potassium.
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
Yes, potassium is more reactive than francium. While francium is the most reactive alkali metal, potassium is more commonly found and easier to handle due to its higher atomic number and stability.
Rubidium is more reactive than sodium because rubidium has a larger atomic radius and fewer electron shells, making it easier for rubidium to lose an electron and form a positive ion. This tendency to lose an electron increases its reactivity compared to sodium.
Potassium
Potassium is more reactive than hydrogen. It is a highly reactive metal that reacts violently with water, while hydrogen is a nonmetal gas that is generally unreactive unless under specific conditions.
Sodium
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.
Yes, potassium is more reactive than copper. Potassium is a highly reactive metal, readily reacting with water and air. Copper, on the other hand, is less reactive and does not easily react with water or air under normal conditions.
Potassium is more reactive than sodium. This is because potassium is lower in the alkali metal group and has one more electron, making it more likely to lose that electron and react with other elements.
Yes, rubidium has a higher melting point than potassium. Rubidium has a melting point of 39.3°C, while potassium has a melting point of 63.4°C.
