Ionic Radius

Front

What is ionic radius?

Back

The ionic radius is the measure of an atom's ion in a crystal lattice, representing the size of the ion.

Front

How does the ionic radius change when an atom gains an electron?

Back

The ionic radius increases when an atom gains an electron due to increased electron-electron repulsion.

Front

What is the trend of ionic radius as you move down a group in the periodic table?

Back

The ionic radius increases as you move down a group due to the addition of energy levels.

Front

Which ion has a larger radius: Na⁺ or Na?

Back

Na has a larger radius than Na⁺ because Na⁺ loses an electron.

Front

What happens to the ionic radius when an atom loses an electron?

Back

The ionic radius decreases when an atom loses an electron due to reduced electron-electron repulsion.

Front

Which has a larger ionic radius: Cl or Cl^-?

Back

Cl^- has a larger ionic radius than Cl because it gains an electron.

Front

What is the effect of nuclear charge on ionic radius?

Back

Increased nuclear charge pulls electrons closer, decreasing the ionic radius.

Front

How does the ionic radius of cations compare to their parent atoms?

Back

Cations have a smaller ionic radius than their parent atoms due to loss of electrons.

Front

How does the ionic radius of anions compare to their parent atoms?

Back

Anions have a larger ionic radius than their parent atoms due to gain of electrons.

Front

What is the general trend of ionic radius across a period?

Back

The ionic radius generally decreases across a period due to increasing nuclear charge.
