Chapter 8: Q11CQ (page 338)

Question: The 鈥渞adius of an atom鈥� is a debatable quantity. Why?

Short Answer

Expert verified

Answer

Half the distance between the nuclei of identical neighboring atoms in the solid form of an element.

Step by step solution

01

Radius of the atom

The radius of an atom is about 0.1 nm (1脳10-10m)

The wave function for the electrons in atoms does not have an abrupt change to zero at some specific radius and beyond Instead, the wave function.

02

Explanation.

And therefore the probability density for finding an electron at a given distance from the nucleus falls off exponentially with a tail that extends to infinite distance once the distance is large enough. It is therefore somewhat ambiguous to decide at what distance the probability of finding an electron has become small enough to regard that location as outside the radius of the atom.
