WebbAn octet will contain 0 or 8 valence electrons. An octet is achieved with 0 valence electrons, because the next lower orbit becomes the outermost orbit, and this orbit will always have 8. Exceptions to this rule are H, He and the transition metals. Helium is a noble gas and stable with 2 electrons. Webb22 mars 2024 · If an element is located on the left side of the table (metal) and has less than three valence electrons, it will lose its valence in order to become stable and achieve an octet. In contrast, elements on the right side of the table (nonmetals) will gain up to eight electrons to achieve octet status. Webbför 2 dagar sedan · As selenium is a group 16 element it consists of 6 electrons in its valence shell while fluorine is a group 17 element therefore, all the fluorine atoms have 7 valence electrons. Hence, selenium is short of 2 electrons in obtaining its octet while fluorine atoms require one electron each. お好み焼き作り方
