One mole of 'nickel (6 × 1023 atoms) has a mass of 59 grams, and its density is 8.90 grams per cubic centimeter, so the center-to-center distance between atoms is 2.23 x 10-10 m. You have a long thin bar of 'nickel, 2.3 m long, with a square cross section, 0.10 cm on a side. You hang the rod vertically and attach a 64 kg mass to the bottom, and you observe that the bar becomes 0.721 cm longer. From these measurements, it is possible to determine the stiffness of one interatomic bond in 'nickel.

**Title: Understanding the Interatomic Bonds in Nickel through Simple Experimentation** **Introduction:** One mole of nickel, equivalent to \(6 \times 10^{23}\) atoms, has a mass of 59 grams. The metal's density is specified as 8.90 grams per cubic centimeter. This means the center-to-center distance between individual atoms of nickel measures approximately \(2.23 \times 10^{-10}\) meters. **Experimental Setup:** In this experiment, consider a long, thin bar of nickel, which measures 2.3 meters in length and has a square cross section with each side measuring 0.10 centimeters. **Procedure:** - The nickel rod is suspended vertically. - A mass of 64 kilograms is attached to the lower end of the rod. - Upon adding the mass, the rod lengthens, extending by an additional 0.721 centimeters. **Objective:** Using the extension measurement obtained by applying the mass, we aim to determine the stiffness of a single interatomic bond in the nickel rod. **Conclusion:** The experiment involves calculating the stiffness of interatomic bonds, enhancing the understanding of atomic interactions in solid materials.
