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.

What is the most reactive among Li Na K Rb?
which element is most reactive K Fr or Na ?
Why is sodium less reactive than potassium?
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.
Is sodium an unreactive element?
All the alkali metals (Li, Na, K, Rb, Cs, Fr) are very reactive.
Is Ag more reactive than K?
No: Potassium is much more reactive generally than silver.
What element reacts with H2O to produce H2?
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
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?

What Group 1A elements is the most reactive cs Li K Na?
K

Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
An expression for 9 less than k?
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
Which group of metals is the most reactive?
The alkali metals are the most reactive (Li, K, Na, Rb, Cs, Fr).
Why doesn't potassium react with water when inside the human body?
Because potassium (symbol K) is a metal and very reactive (like sodium, Na ) but in the body fluid it is NOT the metal form, but the 'innocent' ionic (= oxidised, or salty) form: symbolised by K+ and Na+
What is 5 less than k?
k - 5
