    e. Na, Fe, K

    Explanation:

    The group of elements that will be positive charge ions is metal. You can find metal in the first 2 columns of the periodic table and in the transition area. Natrium/sodium (Na), iron (Fe), and kalium/potassium (K) categorized as metal and they will form positive charge ions.

    On the other hand carbon (C), oxygen (O), arsenic (As) and bromine (Br) is gas and will form negative charge ions. Gas located on the right side of the periodic table.
