because it gains an electron, so the positive charge from the nucleus which pulls the electrons in is distributed over more electrons, so the pull on each one is weaker, so the ion is bigger

Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
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 vary with the number of electron added in the formation of anion?
When an electron is added to an atom, its size increases due to increase in repulsions between the electrons.
What does anion do as you go across the periodic table?
An anion, simply carries across the atom numbers, in greater size. But that is only with the metals, with non-metals, the numbers are arranged by how less the number is. So the higher the atom number, the further across will the anion be on the Periodic table but with non-metals, the less the atom number the closer to the metal section will the anion be on the Periodic table.
Who have high mobility cation or anion?
The mobility of ions depend upon the size of ions. If you take two ions out of which one is cation and one is anion, then the mobility of cation will be more due to its smaller size. Foe example:- From Na+ and F- ions, sodium ion has higher mobility.
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
Were Paul Bunyan's parents the same size as him?
no he was bigger than his parent
The size of Cl- ion is larger than Cl atom?
As one electron is addded to the clorine, repulsion among the electrons are higher => and repulsion makes the clorine anion bigger.
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.
Why is an anion larger than its parent atom?
The size of an anion is larger than its parent atom because anions are formed due to the gain of electrons. When the electrons increase, there are still the same number of protons. The attractive force is thus reduced as there are the same number of protons attracting an increased number of electrons. This causes the electrons to not be bound as tightly to the nucleus resulting in an increase in size. In other words, anions have one or more extra electrons that contribute to the size of the atom. These extra electrons increase its size and make it larger than the neutral atom.
Why the ionic radii of negative ions are larger than the size of their parent atom?
because when electron are aded to form a anion , the increase of electron_elctron repulsion cause the elcectron to spread out in more spaces
Is size 4 shoes bigger or size 6?
Size 6 shoes are bigger. The bigger the number, the bigger the shoes!
How does the size of an atom change when it is converted to an anion and a cation?
A cation is an element that loses electrons in order to achieve a pseudo-noble gas electron configuration:Hence, when a cation loses electrons it has an uneven number of (p+) and (e-). The protons then pull harder on the electrons or (e-) because there is more positive charged subatomic particles than there are negatively charged subatomic particles. The remaining electrons are closer to the nucleus making the cation smaller in size than the original atom.
Are nonmetals bigger than metals?
Non-metal ions typically form negative ions (ie: Cl-) Therefore they now have an extra electron which is protected from the positive pull of the nucleus by the other electrons and therefore the electron shell has now expanded, making nonmetal ions larger than nonmetal atoms
Is king size bigger than queen size?
The king is bigger.
What size is a Texas king size bed?
The size of a king size bed. But bigger. Everything's bigger in Texas.
How does a polarised anion differ from an unpolarised anion?
Well the difference will be in the type of bond formed as a result. The bond would be Ionic in case of polarized anion and Covalent in case or unpolarised anion.The related link below also talks about the size of the anion and charge density in determining the bond type.
