The following paragraph is a description of the fictional element melbournium (Mb). Mb in its elemental form, is a solid at room temperature. There are 38 protons in its nucleus. The sample of Mb in my laboratory has 40 neutrons. Its electronegativity is 0.5. I have been told that there is only one other isotope of Mb with 38 neutrons (which is 50% abundant). All the information you require about Mb to answer the questions below is supplied in the statement above (it is a fictional element, so it is not on The Periodic Table). Data for F (fluorine), mentioned below, can be sourced from the Periodic Table. I. Determine the atomic number of Mb. II. Determine the mass number of the isotope that I have in my lab. III. Determine how many electrons are in Mb. IV Write the full electronic configuration of Mb using the correct rules for the energy levels. V. Will Mb gain or lose electrons (and how many) to form an octet? Why? VI. Determine what type of ion (and the value) Mb will form. VII. Deduce what type of substance Mb is in its elemental form (metal or non-metal) VIII. Determine by calculation if a compound formed between Mb and F will be covalent or ionic (use using ΔEN values).
