What is the purpose of electron configurations?

• To predict ground state

• All of the above

• To indicate valence shell and valence electron for determining chemical behavior

• To assist in making predictions on ways certain elements may react

Why is the 4s shell filled before the 3d shell?

• The energy of 4s is higher than that of 3d

• The energy of 4s is lower than that of 3d

• The 4s shell is farther from the nucleus than the 3d shell

• The 4s shell is closer to the nucleus than the 3d shell

What is the purpose of the Aufbau Principle?

• To determine the orbital shape

• To indicate the order in which subshells of an atom are filled with electrons

• To determine the opposing spins of electrons in filled orbitals

• To determine the maximum number of electrons that can occupy an orbital

What is the purpose of Hund’s Rule?

• To determine the orbital shape

• To indicate the order in which subshells of an atom are filled with electrons

• To determine the maximum number of electrons that can occupy an orbital

• To determine the opposing spins of electrons in filled orbitals
