The neutral atom of potassium has the largest radius.
Look at your periodic table and you will see that K, potassium, must have the largest radius of these choices. You know that, K + and Na + will be small in radius because they have donated an electron to become positively charged cations.
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
K+
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
aldosterone
Potassium has the largest atomic radius.
Look at your periodic table and you will see that K, potassium, must have the largest radius of these choices. You know that, K + and Na + will be small in radius because they have donated an electron to become positively charged cations.
K
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Na+-K+ ATPase
K+
A+ Na
apex says : "K"
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
aldosterone
The binding of Na+ ions to the pump
