neutral K atom has 19 electrons with electronic configuration of 2,8,8,1 but K +1 has 18 electrons with electronic configuration of 2,8,8. Thus removing an electron from neutral k atom means only 3 energy shells in k ion as compared to 4 shells in a neutral k atom. Lesser shells means more close to nucleus, thus more attraction by the nucleus which means smaller atomic size. It has one less shell containing electrons.
What else can I help you with?
What is the radius of a potassium atom is larger than a radius of potassium ion in the ground state?
This occurs because a potassium atom has one more electron than a potassium ion in the ground state; the extra electron increases the size of the atom due to increased electron-electron repulsion, leading to a larger atomic radius than the potassium ion.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.
What can be concluded if an ion of an element is smaller than an atom of the same element?
If an ion of an element is smaller than an atom of the same element, it suggests that the ion has lost electrons compared to the neutral atom. When electrons are lost, the outer electron shell contracts, making the ion smaller. This typically occurs when an element forms a positive ion by losing one or more electrons.
How is a potassium atom (K) different from a potassium ion (K )?
Potassium consists of potassium atoms with their valence electrons delocalized throughout the metal, put those electrons still essentially "belong" to their atoms. A potassium ion is a potassium atom that has lost its valence electron to another atom molecule or ion and therefore carries a 1+ charge.
Is a rubidium larger or smaller than a neutral atom?
A rubidium atom is larger than a neutral atom because, when it loses an electron to become an ion, it loses an electron from the outermost shell, increasing the effective nuclear charge which attracts the remaining electrons closer to the nucleus, reducing the size of the ion compared to the atom.
Is potassium ion larger then a potassium atom?
No, it is smaller
What is the radius of a potassium atom is larger than a radius of potassium ion in the ground state?
This occurs because a potassium atom has one more electron than a potassium ion in the ground state; the extra electron increases the size of the atom due to increased electron-electron repulsion, leading to a larger atomic radius than the potassium ion.
When Mg forms an ion will the ion be smaller or longer than the atom?
The ion has a smaller diameter.
Which is more highly oxidized a potassium atom or a K1 ion?
A K1 ion is more highly oxidized than a potassium atom. This is because the K1 ion has lost an electron, leaving it with a +1 charge and making it more positively charged than the neutral potassium atom.
Why size of hydrogen ion is greater than its atom?
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
A positive ion is generally smaller in size than the neutral form from which it forms. This is because when an atom loses an electron to become a positive ion, the remaining electrons experience a stronger attraction to the nucleus, leading to a more compact arrangement.

Is a positive ion smaller or larger than its parent atom?
A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.
Why potassium carbonate is more basic than cesium carbonate?
Potassium carbonate is more basic than cesium carbonate because the potassium ion is smaller in size than the cesium ion, leading to stronger electrostatic attraction between the potassium ion and the carbonate ion. This results in easier dissociation of the hydroxide ions, making potassium carbonate more basic.
What is e major atom in potassium?
The major atom in potassium is the potassium ion, which has a positive charge of +1 and a single electron in its outermost shell. This ion is stable and commonly found in compounds like potassium chloride (KCl) and potassium hydroxide (KOH).
