Fill in the blank with the appropriate numbers for both electrons and bonds(considering that single bonds are counted as one, double bonds as two, and triple bonds as three).12345678

1. fluorine has valence electrons and makes bond(s) in compounds.2 oxygen has valence electrons and makes bond (s) in compounds.3. nitrogen has valence electrons and makes bond(s) in compounds.4. carbon has valence electrons and makes bond(s) in compounds.

1.Fluorine is having 7 number of electrons and 1 makes bond.

     Electronic configuration  -  1S² 2S² 2P⁵  

    1 electron need to get in stable states 2P⁶.

2.Oxygen is having 6 balance electron and 2 makes bonds.

    Electronic configuration  -  1S² 2S² 2P⁴  

   2 electron need to get in stable states 2P⁶.

3.Nitrogen is having 5 balance electron and 3 makes bonds.

    Electronic configuration  -  1S² 2S² 2P³

    3 electron need to get in stable states 2P⁶.

4. Carbon having 4 balance electron and 4  makes bonds.

    Electronic configuration  -  1S² 2S² 2P²

     4 electron need to get in stable states 2P⁶.
