Question

A Review Constants Periodic Table Learning Goal: To use electron configuration to explain magnetic behavior. Electron configuration The magnetic behavior of an atom or ion depends on its electron configuration. An important property that results from the electron configuration of an atom or an ion is behavior in the presence of an external magnetic field. Due to the random orientations of electron spins most materials have no permanent magnetic effect without an external magnetic field. Part A Select the correct electron configurations from the list below. You can refer to the periodic table for atomic numbers. Check all that apply. ► View Available Hint(s) The electron configuration of Cis He]2s22p? The electron configuration of Autis Xe4f145dº6s1 The electron configuration of Csis [Xe]6sº5d". The electron configuration of Co is [Ar]483d7 The electron configuration of 02.is He]2s22p. Submit Previous Answers X Incorrect; Try Again; 4 attempts remaining At least one of the options is incorrect. Recall that the electron configuration of a neutral Au atom is [Xe]4f45d1ºs. During the formation of a cation (positive ion) for transition metals electrons are often removed from the s orbital first (depending on the stability of the resulting cation). You may want to review Hint 3. Identify how electrons are removed from transition metals.

Answer 1

Answer : -

These questions are answered by using the simple of diamagnetic and paramagnetic substance and the electronic configuration.
