No, sodium reacts more than potassium. More violently also. The electrons surrounding the sodium atom are closer together (tighter to the nucleus of the atom) and this results in more energy needing to be used to rip them off. To test this, you could get a bucket of water (H20) and put some pure potassium in it. The try some pure sodium. Watch which one will have a greater reaction. (The potassium should fume, possibly ignite. The sodium should on the other hand ignite then explode). Lithium has an even greater reaction than these two. As you work your way up the alkali metals group in the Periodic Table (Group or column 1) the reactions intensify between the metals and solutions, such as water. Li>Na>K>Rb>Cs>Fr
It works like this for reactions of almost any element. The element directly above should be more reactive than itself.
No, potassium is more electropositive than sodium.
No. Potassium is just another element.
The ionisation enthalpy of potassium is lower than that of sodium.
More permeable to K than Na
Potassium salt is not better; it is recommended for some diets without sodium.
sodium because it's the first group and first group are the most
If you experience excessive fluid loss, through vomiting, diarrhea, or sweating, or if you take certain medications, you may be at risk for potassium deficiency. In addition, a diet that is high in sodium and low in potassium can negatively affect potassium status. The Standard American Diet (SAD), which is high in sodium-containing processed foods and low in fruits and vegetables, contains about two times more sodium than potassium. Many health experts recommend taking in at least five times more potassium than sodium. The symptoms of potassium deficiency include muscle weakness, confusion, irritability, fatigue, and heart disturbances. Athletes with low potassium stores may tire more easily during exercise, as potassium deficiency causes a decrease in glycogen (the fuel used by exercising muscles) storage.
Potassium has a lower electronegativity value than sodium, meaning (among other things) that it gives up an electron more readily, and therefore displaces hydrogen more readily, than sodium does.
Potassium is more reactive than sodium
Metals which are more reactive than aluminium. Eg= Sodium, Magnesium, Potassium, etc
Potassium
Case to case basis. In my case diclofenac potassium is more powerful than diclofenac sodium.
Potassium reacts faster and violently with acids than sodium.
CaO is not expected to react with sodium hydroxide because sodium is more reactive than calcium.
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.
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.
during depolarization
Sodium
Sodium is produced more economically and thus is much lower cost than potassium. Sodium is also slightly easier to handle. Both are used extensively in industry but sodium metal is less reactive than potassium metal.
