Use the periodic trends to predict the relative size of the following transition metals: Ta, Hf, La, W Enter your answers as 1, 2, 3, and 4. A rank of "1" represents the smallest atom and a "4" represents the largest atom. Ta = Hf = La = W =

Step 1
Atomic size generally increases down a group in the periodic table due to the addition of electron shells, and it generally decreases across a period from left to right due to increased nuclear charge pulling the electrons closer to the nucleus. Show more…
