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.

Does sodium have the larger first ionization energy than potassium?

No, potassium has a larger first ionization energy than sodium. Potassium has an extra electron in its valence shell compared to sodium, making it more difficult to remove an electron from a potassium atom compared to a sodium atom.


What is electronegativity difference between hydrogen and sodium atom?

The electronegativity difference between hydrogen and sodium atoms is approximately 2.1. This means that hydrogen atom is more electronegative compared to sodium atom. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.


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 are the ionisation enthalpies of potassium and sodium?

The first ionization energy of potassium is 419 kJ/mol, while the first ionization energy of sodium is 496 kJ/mol. This means that it requires less energy to remove an electron from a potassium atom compared to a sodium atom.


Would an atom of sodium and an atom of potassium join to form and ionic clumping?

Yes, an atom of sodium with a +1 charge could potentially join with an atom of potassium with a +1 charge to form an ionic bond. This could lead to the formation of a crystal lattice structure, rather than a clumping of individual atoms.

What is the difference in mass of Na ion and Na atom?

The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.

What is the difference between potassium chloride and potassium nitrate?

The difference between potassium nitrate and potassium sulphate is that the potassium nitrate is superior to potassium sulphate. The potassium nitrate has high solubility while the potassium sulphate has moderate solubility.


What is difference between potassium atom and molecule?

an atom is a nucleus,[ nutrons and protons] and a number of electrons whirring around it. a molecule is a combination of two or more atoms to make something new


Predict the nature of the bond between a potassium atom and chlorine atom. The electronegativity of K is 0.8 and Cl is 3.0?

The bond between potassium (K) and chlorine (Cl) is ionic because the electronegativity difference between them is large (2.2). Potassium will donate its electron to chlorine, forming K+ and Cl- ions that are attracted to each other by electrostatic forces, creating an ionic bond.


How is a sodium atom different from a sodium atom?

The only possible long-lasting difference between two isolated sodium atoms is that one has more neutrons in its nucleus than the other, so that they are distinct isotopes of sodium. For a short time, atoms of the same isotope of sodium can also be different because one is more excited than the other.


Why is it imposible for sodium to unite chemically with potassium?

Sodium and Potassium belong to group one of the Periodic table. They both contain one electron in their outer shell. They form a chemical bond by donating the outer shell electron to another atom. The other atom will tend to accept electrons rather than donate them. Since sodium and potassium both donate electrons they cannot form a chemical bond with each other.
