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 approximately 39.10 atomic mass units.
What is the atomic symbol for K?
The atomic weight of K (Potassium) is 39.0983 g/mol
Is sodium molecular or atomic?
Sodium is atomic / metallic.
What is the atomic number of potassium and sodium?
Potassium is a non metal element. Atomic number of it is 39.
How does its potassium atomic radius compare to that of sodium?
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
How does potassiums atomic radius compare to that of sodium?
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
Why sodium has more density than 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.
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.
Which has more mass a mole of potassium or a mole of sodium?
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
What does the K stand for on the periodic table?
Potassium
What has a larger atomic radius sodium or potassium?
Potassium has a larger atomic radius than sodium. This is because as you move down a group in the periodic table, atomic size generally increases due to additional electron shells being added, leading to increased electron-electron repulsion and a larger atomic radius.
Sodium reacts with water less vigorously than potassium. why?
Sodium reacts less vigorously with water compared to potassium because sodium has a larger atomic size and lower reactivity than potassium. This results in a slower reaction rate and less violent release of hydrogen gas.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
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.
