? Match the atoms to their correct electron configuration. You can refer to the periodic table to do so. Drag the items on the left to the correct location on the right. fluorine (F) (Ar) 452 sodium (Na) 152252 2ps helium (He) [Ne] 3s calcium (Ca) 152 2s22p nitrogen (N) [Ne] 352 3p4 sulfur (5) 152​

hope you got the answer

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
