What is the atomic number of potassium and sodium?
Potassium is a non metal element. Atomic number of it is 39.
What has the largest radius K or Na?
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.
What is the atomic mass of potassium?
The atomic mass of potassium is 39.0893
What substances are transported by active transport?
Sodium Potassium
What three minerals control cellular fluid balance?
sodium and potassium
What is the atomic number of potassium and sodium?
Potassium is a non metal element. Atomic number of it is 39.
What is the difference between a sodium atom and a potassium atom?
Sodium and potassium are two different albeit similar elements. A neutral sodium atom has 11 protons, 11 electrons and typically 12 neutrons. It forms and ion with 10 electrons. It has an atomic radius of 186 picometers. Potassium has a large, heavier atom than sodium A neutral potassium atom has 19 protons, 19 electrons ans usually 20 neutrons. It forms an ion with 18 electrons. Potassium's atomic radius is 227 picometers. Additionally, potassium is somewhat more reactive than sodium and has a lower melting point.
What is the largest element of Period 3 on the Periodic table?
Sodium has the largest atomic size in the third period.
What has the largest radius K or Na?
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.
Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
Of the following elements which one would have the largest ionization energy Hydrogen (H atomic 1) Cesium (Cs atomic 55) Sodium (Na atomic 11) Potassium (K atomic 19)?
Hydrogen.
What is the symbol for sodium potassium?
Sodium is Na Potassium is K
What is the atomic mass of potassium?
The atomic mass of potassium is 39.0893
Why sodium is more reactive than 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.
