    F.

    Fluorine has 7 valence electrons

    2-7

    Potassium has 1 valence electron

    2-8-8-1

    Carbon has 4 valence electrons

    2-4

    and Helium has 2 valence electrons

    2

    All atoms lose or gain electrons from chemical bonds in order to have a full valence shell, which for most atoms is 8.

    Potassium would lose 1 electron, giving it a full valence shell

    Carbon needs to gain 4 electrons

    Fluorine needs to gain 1 electron

    and Helium already has a full valence shell.

    Fluorine only needs one electron, so it is more likely it will gain one, than it is that carbon gains 4.

    Chlorine particularly features an electron while forming bonds. the respond is Sodium and Potassium via fact the two in trouble-free terms have one valence electron, and a standard way of understanding that's via fact they're the two interior the 1st column of the periodic table. considering that they simply has one valence electron, they go with to do away with it so as that they could kind a competent octet. in evaluation, Chlorine in trouble-free terms desires one electron to kind a competent octet, so it features an electron while forming bonds.

    [Answer: Of your list, fluorine (F) is the most electronegative; therefore, it has the greatest tendency to accept another electron to stabilize its outer shell to complete its octet, which would be missing one electron.]
