Question

in its ground state? Which of the following atoms is paramagnetic B) bariwm (ba) O cadmium (Cd 1D) ymerbium (Yb) E) argon (Ar) 16. ー 17. Which of the following statenments is true? The kpion Is orbital is smaller than the helium is cebital because krypton's nuclear charge draws the electrons closer because krypton's p The krypton 1s oebital is smaller than the helium Is orbital and d orbitals crowd the s orbitals B) C) The krypton Is orbital and the helium Is orbital are the same size because orbitals can have cnly two electrons The krypton 1s orbital is larger than the bellum 1s orbital because krypton contains more electrons D) E) The krpton is orbital is larger than the helium Is orbital because krypton's onization energy is lower so it's easier to remove electrons 18.

A) CI B) P C) Na D) S 19. E) Si 20. The change in energy for which of the following processes represents the first ionization energy of bromine? A) Bris) → Br'.(g) + 2e- 2 Br-(g)→ Br, () +2e- Br(g) →Br.(g)+2e- C) E)
