How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
Would the same behavior exist in atomic radius for the ions of atoms?
No, the behavior of atomic radius for ions of atoms would not be the same. When an atom gains or loses electrons to become an ion, its radius changes. Cations (positively charged ions) are smaller in radius compared to their parent atoms because they lose electrons, leading to increased effective nuclear charge pulling the remaining electrons closer. Anions (negatively charged ions) are larger in radius as they gain electrons, resulting in increased electron-electron repulsion and expansion of the electron cloud.
What is the relationship between the radius of a anion and that of the atom from which it is formed?
An anion is formed by gaining electrons, leading to an increase in the electron cloud's size compared to the original atom. This enlargement results in the anion having a larger ionic radius than the neutral atom from which it originated.
Why are cations smaller than parent ions?
Cations and their parent atoms have the same number of protons in the nucleus but different numbers of electrons. As cations have less number of electrons, the effective nuclear charge increases and as such,the remaining electrons are more tightly bound by the nucleus. Thus, cations are smaller in size compared to their parent atoms.
Which has a higher covalent radius cations or noble gases?
noble gases have larger radius than cations.

Sodium chloride and caesium chloride have different structure?
because they both have different radius ratio so they have different structure. radius ratio=radius of cations/ radius of anions

What happens to the ionic radius values of the cations(-) as you move across period 2?
The ionc radius of lithium is bigger compared to beryllium.
How do sizes of atoms of alkali metals compared to their positive ions?
The atomic radius of cations is lower.
What is the relationship between the radius of a anion and that of the atom from which it is formed?
An anion is formed by gaining electrons, leading to an increase in the electron cloud's size compared to the original atom. This enlargement results in the anion having a larger ionic radius than the neutral atom from which it originated.
What are anions of a particular element generally larger than the atoms of the same element?
Its C. Anions gain electrons without gaining protons. This increased negative charge with no increase in positive charge allows electrons to orbit farther from the nucleus; therefore the ions are larger.
Why are cations smaller than parent ions?
Cations and their parent atoms have the same number of protons in the nucleus but different numbers of electrons. As cations have less number of electrons, the effective nuclear charge increases and as such,the remaining electrons are more tightly bound by the nucleus. Thus, cations are smaller in size compared to their parent atoms.
Which Has a larger ionic radius oxygen or fluorine?
Fluorine has a larger ionic radius than oxygen because fluorine is higher up in the periodic table with fewer protons in its nucleus, resulting in a larger atomic radius compared to oxygen.
Which one has the larger radius potassium ion or bromide ion?
The bromide ion has a larger radius than the potassium ion. This is because bromine has more electron shells than potassium, resulting in a larger atomic radius and thus a larger ionic radius for bromide compared to potassium.
