Sodium and potassium are both highly reactive because they have only one outer shell electron which they lose very easily to form Na+ and K+ ions respectively.
The sodium and potassium in the body are already in the form of these ions.
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.
Potassium can displace sodium, as potassium is more reactive than sodium. When potassium is added to a solution containing sodium ions, a displacement reaction can occur where potassium replaces sodium in the chemical compound.
Sodium is preferred over potassium in industrial applications because it is more abundant, cheaper to produce, and has better chemical stability. Additionally, sodium is more reactive and versatile than potassium, making it more suitable for a wide range of industrial processes.
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.
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).
Sodium
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
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.
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.
No, titanium is less reactive than sodium.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.
The question isn't very specific (preferred for what?!), but sodium metal is less reactive than potassium. It is also slightly more abundant than potassium on Earth.
sodium because it's the first group and first group are the most
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.
Aluminium is in the middle of the reactivity series of metals. It is more reactive than copper, silver, and gold, but less reactive than sodium, potassium, and calcium.
