What is the electron configuration for Og with a charge of 2-? I was writing a cool program that determines the electron configuration of elements for me, and I wondered what would happen if you went over 118 &mdash; the "limit" of my program.  So, what is the electron configuration after you go over 118 electrons?
According to SCF Relativistic Hartree–Fock Calculations on the Superheavy Elements 118–131 J. Chem. Phys. 53, 2397 (1970), for neutral atoms:

119 $8s$

120 $8s^2$

121 $8p8s^2$

122 $7d8p8s^2$

123 $6f7d8p8s^2$

124 $6f^38p8s^2$

125 $5g6f^38p8s^2$

126 $5g^26f^28p^28s^2$

127 $5g^36f^28p^28s^2$

128 $5g^46f^28p^28s^2$

129 $5g^56f^28p^28s^2$

130 $5g^66f^28p^28s^2$

131 $5g^76f^28p^28s^2$

Later calculations reported in Electronic Configurations of Superheavy Elements J. Phys. Soc. Jpn. 65, pp. 3175-3179 (1996) are different starting with element 122:

122 $8p^28s^2$

123 $6f7d8p8s^2$

124 $6f^28p^28s^2$

125 $6f^48p8s^2$

126 $5g6f^48p8s^2$

127 $5g^26f^38p^28s^2$

128 $5g^36f^38p^28s^2$

129 $5g^46f^38p^28s^2$

130 $5g^56f^38p^28s^2$

131 $5g^66f^38p^28s^2$

However, Electronic structure of eka-thorium (element 122)
compared with thorium J. Phys. B: At. Mol. Opt. Phys. 35 (2002) 1693–1700 finds:  

122 $7d8p8s^2$

specifically agreeing with the 1970 paper and disagreeing with the 1996 paper.
