There is an increase in density of elements from titanium ($Z = 22$) to copper ($Z = 29$) in the 3d series of transition elements.
Answer
Answer
AIBecause the atomic size decreases (nuclear charge increases) from Ti to Cu while atomic mass increases, so the mass per unit volume, i.e. density, increases.
