WebDo not use separator between noble gas and orbital. 1. Co: 2. Co² 3. Co. Write electron configurations, in shorthand notation, for the following: Co, Co²+ and Co. Quantity of electrons enclose in brackets (for example [Xe]6s (2)5d (3) etc.). Do not use separator between noble gas and orbital. 1. Co: 2. The elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation. The elements that form bonds by donating electrons are called cations. The rubidium atom donates an electron of the last shell to form bonds and turns into a rubidium ion(Rb+). That is, … Meer weergeven The nucleus is located in the center of the atom.
