Final Answer:
The magnitude of charge q₁ is not provided in the question. Regarding the electronic configuration of barium (Ba), the correct option is C) 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 6s¹. (Option C)
Step-by-step explanation:
The question does not specify the magnitude of charge (q₁), so it is not possible to determine the numerical value or sign of the charge without additional information.
For the electronic configuration of barium (Ba), the correct representation is provided in option C. Barium has an atomic number of 56, and its electronic configuration follows the filling order of electrons in the various atomic orbitals up to the 6s subshell. The correct representation is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 6s¹, indicating the distribution of electrons in the different energy levels and subshells.
Understanding the electronic configuration of an element is crucial in chemistry as it provides insights into its chemical behavior and reactivity. The arrangement of electrons in atomic orbitals follows specific rules and principles, such as the Aufbau principle and Pauli exclusion principle, governing the filling order and occupancy of electrons in an atom's electron shells. (Option C)
