Atomic radii
Understand the Problem
The question is about atomic radii, which relate to the size of atoms, often in the context of chemistry or physics. It may require a search for definitions, trends in periodic tables, or explanations of factors influencing atomic radius.
Answer
The distance from the nucleus to the outermost orbital of its electron.
The atomic radius of a chemical element is the distance from the nucleus to the outermost orbital of its electron.
Answer for screen readers
The atomic radius of a chemical element is the distance from the nucleus to the outermost orbital of its electron.
More Information
Atomic radius is a key concept in chemistry, helping to determine the size and volume of different elements and their chemical behavior.
Tips
A common mistake is to think atomic radius is measured from the nucleus to the outer edge of an electron cloud as if it's a precise boundary, instead, it represents an average distance.
