Question

D1. Do atoms generally get bigger or smaller as you go down a group in the periodic table?
D2. Do atoms generally get bigger or smaller as you go across a period from left to right in the periodic table?
D3. How do the trends in ionization energies compare to the trends in atomic size?

Answer to D1: Atoms generally get bigger as you go down a group in the periodic table. This is because each successive element has an additional electron shell, increasing the atomic radius. Answer to D2: Atoms generally get smaller as you go across a period from left to right in the periodic table. This is due to the increase in nuclear charge, which pulls the electron cloud closer to the nucleus, reducing the atomic radius. Answer to D3: The trends in ionization energies are generally opposite to the trends in atomic size. As atomic size decreases across a period, ionization energy increases because electrons are held more tightly by the nucleus. Conversely, as atomic size increases down a group, ionization energy decreases because electrons are further from the nucleus and are more easily removed.
