The atomic number of an element represents the number of protons in the nucleus of its atom.
The element with an atomic number of 37 is Rubidium (Rb).
To determine the electron configuration of Rubidium, we first need to know the order in which the electrons fill the different energy levels and orbitals.
The electron configuration follows the Aufbau principle, which states that electrons fill the lowest energy levels and orbitals first before moving to higher energy levels and orbitals.
The electron configuration of Rubidium (Rb) is: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s¹
This can also be written in the abbreviated form as: [Kr] 5s¹
Note: The electron configuration [Kr] represents the electron configuration of the noble gas Krypton (Kr). The [Kr] indicates that all of the inner shells (1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶) are already filled and we only need to consider the outermost shell (5s¹).
