which is the electron configuration for nobelium (no)? rn7s²5f¹⁴ rn7s²5f⁷ ne3s²3p⁷ xe6s²5d¹
Answer
Brief Explanations:
Nobelium (No) has an atomic number of 102. Using the noble - gas core notation, we start with the previous noble gas radon (Rn). After Rn, the electron filling follows the order of sub - shells. The 7s sub - shell fills first with 2 electrons and then the 5f sub - shell fills completely with 14 electrons for nobelium. The other options have incorrect noble - gas cores or incorrect sub - shell electron counts.
Answer:
[Rn]7s²5f¹⁴
