In an oxide ion, electrons get added. This means, lesser nuclear charge. This is due to screening effect. The inner electrons shield the outer electron from the nuclear charge which is why the outer electrons get relatively lesser nuclear charge. So, more electrons means lesser nuclear charge.
Consider a person standing in front of you. You get blocked from the view in front of you. Suppose two more people stand in front of you. Now, it is more difficult for you to catch a glimpse of the front view than it was before.
This is exactly what happens in the oxide ion.
Lesser nuclear charge means the electrons do not get pulled towards the nucleus as they were before, i.e., in the oxide ion, the electrons do not get pulled towards the nucleus as they were in the neutral oxygen atom.So, the electrons will be farther than they originally were.Thus, an oxide ion is larger than an oxygen atom.

When electron transfer results in an ion larger than the original atom?
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
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. =]
What one is larger a chlorine atom or a chloride ion?
anion is always larger than 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.
Why is the chloride ion larger than the chloride atom?
The chloride ion is an anion, having one more electron than the chlorine atom.
Is a chlorine atom or chlorine ion bigger?
A sulfur atom is larger than an oxygen atom.
When electron transfer results in an ion larger than the original atom?
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
When an atom of chlorine forms an ionic bond with an atom of sodium does the atom of chlorine become an ion with a smaller or larger radius than the atom of chlorine?
It becomes an ion with a larger radius than the atom of chlorine
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. =]
A negative ion is than its parent atom?
A negative ion is larger than its parent atom because of its additional electron(s).
What one is larger a chlorine atom or a chloride ion?
anion is always larger than 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.
Why is the chloride ion larger than the chloride atom?
The chloride ion is an anion, having one more electron than the chlorine atom.
Is halide atom larger than the halide ion?
Yes
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
Is a sodium atom is larger than a silicon atom?
No. A cesium atom is larger both in terms of atomic mass and atomic radius.
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.
