To explain the increase in density of elements from titanium (Z = 22) to copper (Z = 29) in the 3d series of transition elements, we can break down the explanation into several steps: ### Step 1: Understanding the Elements in the 3d Series The 3d series of transition elements includes titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn). We will focus on the first eight elements from titanium to copper. ### Step 2: Atomic Number and Mass As we move from titanium to copper, the atomic number (Z) increases from 22 to 29. This increase in atomic number corresponds to an increase in the number of protons and, generally, the number of neutrons in the nucleus, leading to an increase in atomic mass. ...
