Which of the Following Statements Is True

question 57

Multiple Choice

Which of the following statements is true?

• A) The krypton 1s orbital is smaller than the helium 1s orbital because krypton's p and d orbitals crowd the s orbitals.
• B) The krypton 1s orbital is larger than the helium 1s orbital because krypton contains more electrons.
• C) The krypton 1s orbital is smaller than the helium 1s orbital because krypton's nuclear charge draws the electrons closer.
• D) The krypton 1s orbital and helium 1s orbital are the same size because both s orbitals can only have two electrons.
• E) The krypton 1s orbital is larger than the helium 1s orbital because krypton's ionization energy is lower so it's easier to remove electrons.
