As one electron is addded to the clorine, repulsion among the electrons are higher => and repulsion makes the clorine anion bigger.
The size of the ion is larger than the size of the neutral atom.
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.
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.
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
anion is always larger than its parent atom

Iodine gains one electron to form iodide ion. The size of iodide ion is larger than the size of iodine atom.
The size of a negative ion is larger than atom. This makes more negative than positive, allowing the negative electrons to go farther from the nucleus.
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.
A sulfur atom is larger than an oxygen atom.
The size will be H- ion > H atom > H+ ion
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
It becomes an ion with a larger radius than the atom of chlorine
A negative ion is larger than its parent atom because of its additional electron(s).
anion is always larger than its parent atom
Larger because a negative ion contains more electrons than its parent atom therefore it is larger. A positive ion would be smaller because it has less electrons than its parent atom.
The chloride ion is an anion, having one more electron than the chlorine atom.
