Chapter 11, Problem 1ALQ

ow does probability ?t into the description of the atom?

Interpretation Introduction

Interpretation:

How the concept of probability fit into the description of the atom should be explained?

Concept Introduction:

Probability is a mathematical concept which is defined as the chances of a particular event.

Answer to Problem 1ALQ

The concept of probability is associated with the description of atom particularly for describing the location of electrons.

Explanation of Solution

Atom contains one nucleus and some orbits in which electrons revolve. Each orbit again contains sub orbit and each sub orbit contains some definite number of orbitals. Electrons are actually present in orbital. An orbital is a three dimensional space where probability of finding electron is maximum. Similarly, node is a space where probability of finding electron is zero.

Conclusion

Probability is used to define orbitals and nodes. Orbitals have maximum probability of finding an electron whereas nodes have minimum probability of finding an electron.
