The size of a positive ion is smaller than the size of its neutral atom. This is because a positive ion has lost one or more electrons. Because there are less electrons than protons, the protons have a stronger pull on the electrons. Consequently, the protons pull the electrons in and the ionic radius decreases.

In the case of the Lithium ion, it has lost one electron, so it is smaller than its neutral atom.

How does the size of a negative ion compare to the size of the atom that formed it?

A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.


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.


If an atom has four valence electrons is it an anion?

No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.


How does the ionic radius of a typical anion compare with radius for corresponding neutral atom?

The ionic radius of a typical anion is larger than the radius of the corresponding neutral atom. This is because when an atom gains an electron to become an anion, the extra electron increases the electron-electron repulsion, causing the electron cloud to expand, resulting in a larger ionic radius.


The size of Cl- ion is larger than Cl atom?

Yes, the Cl- ion is larger than the Cl atom because the addition of an extra electron leads to an increase in electron-electron repulsions, which causes the electron cloud to expand. This results in the formation of an anion (Cl-) that is larger in size compared to the neutral atom (Cl).

How is the size of an anion different from the size of the atom from which it was formed?

Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.


How does the size of each compare with the size of the neutral atom form which it is formed?
