Identify the monoatomic ion that has the following properties.

a. 11 protons and 10 total electrons


b. 9 protons and 8 valence electrons


c. 47 protons and 46 total electrons


d. 28 protons and 26 total electrons


  • chemistry -

    All look ok except for b.
    9+ and 8- gives F+
    9 protons and 9 electrons = Fo which we write as F2.
    9 protons and 10 electrons = F^-

  • chemistry -

    50 protons 68 neutrons and 46 electrons
