Some ions don't change the size of the atom (of course, size is very ambiguous for something as small and tenuous as an atom). The prevailing planetary models of atoms determine the theoretical size of an atom based on which subshell is gaining or losing electrons. For example, if an atom gains an electron that starts filling the next available shell, it would get larger in size. Conversely, if an atom loses the last electron in a shell it would get smaller. In theoretical physics, there are too many other variables that determine an atom's "size" to make this a practicable question (is gaining an electron an endothermic or exothermic reaction? Would losing an electron in some specific circumstance give the remaining atom enough energy to bump the next available electron into the vacated shell, resulting in zero net size change?).
What else can I help you with?
Does chlorine atom has a smaller radius than chlorine ion?
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
Why is a bromide ion larger than a bromine atom?
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
Why does a chloride ion have a larger radius than a chlorine atom?
chlorine ion has one more electron than the chlorine atom, thus the pull of the electrons to the protons in the nucleus is less because of the extra electron allowing the electron cloud to relax a tiny bit
Explain the relationship between the relative size of an ion to its atom and the charge on the ion?
<p><p>if the atoms lose electrons, the ions are relatively smaller than the regular one and they become positively charged. If the atoms gain electrons, the ions are relatively larger than the regular one and they become negatively charged.
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
Why are sodium ions smaller than sodium atoms?
Sodium ions are smaller than sodium atoms because when sodium atoms lose an electron to become an ion, they lose the outermost electron from their electron cloud. This results in a decrease in the electron cloud size around the nucleus, making the ion smaller than the neutral atom.
Why fluorine atom is smaller than fluoride ion?
Fluorine atom is smaller than fluoride ion because when fluorine gains an electron to form the fluoride ion, it adds an electron in the outermost shell which increases the electron-electron repulsion, causing the electron cloud to expand. This expansion results in the fluoride ion being larger in size compared to the fluorine 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.
Would you expect a chlorine ion to be smaller than a magnesium ion?
No, I would expect a chlorine ion to be slightly larger than a magnesium ion. Chlorine gains an electron to form a chloride ion, which increases its electron cloud size, while magnesium loses electrons to form a magnesium ion, making it slightly smaller due to the loss of electron shielding.
Why is nitrogen ion larger than fluoride ion?
The nitride ion has a larger negative charge than the fluoride ion and a smaller positive charge in its nucleus, which means a greater repulsion within the electron shells and a lesser attraction to the nucleus.
Does chlorine atom has a smaller radius than chlorine ion?
Yes, considerably so. In general, positive ions are smaller than their neutral atoms, and negative ions are larger than their neutral atoms.
When iodine becomes an ion is the ion larger or smaller?
When iodine becomes an ion, it typically gains an electron to form a negative ion (iodide ion). This addition of an electron causes the ion to become slightly larger in size due to the increased electron-electron repulsion, which can lead to a slight expansion of its electron cloud and thus the overall size of the ion.
Why is a bromide ion larger than a bromine atom?
Bromide ions are larger than bromine atoms because the ion has one more electron than the neutral atom. The extra electron is less tightly bound than the other electrons because it experiences a smaller effective nuclear charge. Other anions are also larger than their corresponding atoms for the same reason; cations, on the other hand, are smaller than their corresponding atoms because they have fewer electrons.
A calcium atom is larger than a calcium ion because?
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
Is a negative ion larger or smaller than its parent atom?
A negative ion is typically larger than its parent atom. When an atom gains an electron to become a negative ion, the added electron increases the electron-electron repulsions, causing the electron cloud to expand. This expansion results in a larger ionic radius compared to the neutral atom.
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
Is Li plus smaller than Li?
An Na atom is larger as it has one more shell carrying an extra electron that it has not donated yet . In the case of Na (ion) it has lost or donated an electron which means it no longer has the shell that carried the last electron.
