Question

shown below is a periodic table highlighting the elements copper and zinc. copper and zinc are commonly encountered in engineering and construction. based on their atomic weights you would expect zinc to be more dense than copper. however, the density of zinc (zn) is 7.14 g/cm³ compared to 8.96 g/cm³ for copper (cu), and so zinc is actually less dense than copper. for which metal will the separation between the atoms be smaller, copper or zinc (the sizes of copper and zinc atoms are almost exactly the same)? the atomic separation will be smaller for copper the atomic separation will be smaller for zinc dont test me yet, i am trying to gain an understanding before attempting to answer this question. multiple choice 1 point

Explanation:

Step1: Recall density - atomic separation relationship

Density is related to the mass and volume. Smaller atomic separation can lead to higher density if mass is considered.

Step2: Analyze copper and zinc

Copper has a higher density than zinc. Given similar - sized atoms, a metal with higher density likely has smaller atomic separation. So, the atomic separation will be smaller for copper.

Answer:

The atomic separation will be smaller for copper.
