Within which range of atomic numbers,is there a significant increase in the density of these elements?

Options

  1. AFrom Z = 1 to Z = 22.
  2. BFrom Z = 22 to Z = 29.
  3. CFrom Z = 29 to Z = 50.
  4. DFrom Z = 50 to Z = 75.

Correct answer

B. From Z = 22 to Z = 29.

Step-by-step solution

A significant increase in density is noted from titanium (Z = 22) to copper (Z = 29).
