Starting with Calcium (Ca): 
1s2 2s2 2p6 3s2 3p6 4s2 
Next, Sulfur (S):
1s2 2s2 2p6 3s2 3p4 
Adding the first U1 (ununilium) - element 111:
 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2 
 Adding the second P1:
 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2 10s2 
 Moving on to first Sulphur (S):
 1s2 2s2 2p6 3s2 3p3 
 Adding the first S1:
 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2 10s2 5f14 6d10 7p6 
 Adding the second P0:
 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2 10s2 5f14 6d10 7p6 6p1 
 Final configuration: 
 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2 10s2 5f14 6d10 7p6 6p1 1s2 2s2 2p6 3s2 3p3 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d10 7p6 8s2 5g18 6f14 7d10 8p6 9s2 6g2
