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.
Yes, excitable cells like neurons are more permeable to sodium ions than potassium ions. This selective permeability is due to the presence of more sodium channels compared to potassium channels in the cell membrane, allowing sodium to flow into the cell more readily during an action potential.
The ionisation enthalpy of potassium is lower than that of sodium.
Sodium is more reactive than lithium and magnesium but less reactive than potassium.
Potassium and sodium determine the a cell's resting membrane potential. The equilibrium potential (the voltage where no ion would flow) for sodium is about +60 mV while that for potassium is usually around -80 mV, but because the resting cell membrane is approximately 75 times more permeable to potassium than to sodium, the resting potential is closer the the equilibrium potential of potassium. This is because potassium leak channels are always open while sodium come in through voltage gated or ligand gated channels.
Potassium (K) has a lower ionization energy than sodium (Na).
Potassium (K) will react faster with acids than sodium (Na) because potassium is more reactive than sodium due to its lower ionization energy. This makes potassium more likely to displace hydrogen in acids and react more vigorously.
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.
Both potassium and sodium react vigorously with cold water to form metal hydroxides and hydrogen gas. However, the reaction of potassium is more violent and produces a louder explosion due to its higher reactivity compared to sodium. Potassium reacts faster and more violently than sodium in water.
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
Sodium has a higher density than potassium because it has a greater atomic mass per atom. This means that sodium atoms are heavier than potassium atoms, leading to a higher density of sodium compared to potassium.
Well...nothing is so black and white. Some things react differently in different situations. However...it is most likely you'd be using both of these as bases, and as such, KOH - potassium hydroxide - is likely slightly more reactive than NaOH. This is by comparison of their pKa values alone, and many things may factor into reactivity. If anything, they're both very similar in the grand scheme of things.
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, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
Sodium reacts more vigorously with water than potassium because sodium has a lower ionization energy and is more reactive. When sodium comes into contact with water, it forms sodium hydroxide and releases hydrogen gas, resulting in a more rapid and vigorous reaction compared to potassium.
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
As it has more electron shells between the nucleus and the outermost electron, and as group 1 elements react by losing there outermost electron, the more shielding effect between the nucleus and the electron, the smaller the force of attraction on the electron, so the more readily it will react as less energy is needed to break the bond between the outer electron and the positive nucleus.
