A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.

Is the size of a positive ion generally bigger or smaller than the size of the neutral form which it forms?
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. =]
Is a negative ion larger or smaller 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.
Is cation larger than its parent atom?
No. It is smaller.
When an atom loses one or more electrons does the radius of the atom become smaller or larger than the radius of the atom?
please be more specific and I might be able to answer this correctly
What one is larger a chlorine atom or a chloride ion?
anion is always larger than its parent atom

No. It is smaller.
Is a ion larger or smaller than its parent atom?
A negative ion would be considered larger than its parent atom. This is because electrons have mass, which makes the ions gain mass to outgrow their parent atoms.
What is going to happen to the size of a positive ion as compared to the original atom?
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
Is the model of an atom smaller or larger than the actual atom itself?
its larger
Is an atom smaller or larger than basketball?
Smaller
Is molecule larger or smaller than an atom?
Larger.
Is the atom that remains after the nucleus disintegrate larger of smaller than the original atom?
smaller
