which is the electron configuration for nobelium (no)?\nrn7s²5f¹⁴\nrn7s²5f⁷\nne3s²3p⁷\nxe6s²5d¹

Brief Explanations:

Nobelium has an atomic number of 102. The noble - gas core for elements with high atomic numbers is often radon (Rn). After the radon core, the electron filling follows the Aufbau principle. The out - most electrons are in the 7s and 5f orbitals. For nobelium, the electron configuration is [Rn]7s²5f¹⁴ as it has 102 electrons and this configuration follows the rules of electron filling in orbitals.

Answer:

[Rn]7s²5f¹⁴
