In Valence and Crystal Structure, Vol III: Semiconductors, in the paragraph beginning "Group VIIIA elements", there is a sentence beginning "Group VIIIA elements do not readily combining . . .". It should be "combine". In the following sentence "chemist" should be "chemists".

Thank you for the correction Fred, see: http://www.allaboutcircuits.com/vol_3/chpt_2/3.html

Can I suggest the following correct of: "Group VIIIA elements: He, Ne, Ar, Kr, Xe all have 8 electrons in the valence shell. (Figure below) That is, the valence shell is complete. These elements neither donate nor accept electrons. Nor do they readily participate in chemical reactions. Group VIIIA elements do not readily combining with other elements. Though chemist in recent years have forced Xe and Kr to form a few compounds, this is not applicable to our discussion. These elements are good electrical insulators and are gases at room temperature. "

To: "Group VIIIA elements: He, Ne, Ar, Kr, Xe all have 8 electrons in the valence shell. (Figure below) That is, the valence shell is complete meaning these elements neither donate nor accept electrons. Nor do they readily participate in chemical reactions since group VIIIA elements do not easily combine with other elements. In recent years chemists have forced Xe and Kr to form a few compounds, however for the purposes of our discussion this is not applicable. These elements are good electrical insulators and are gases at room temperature.
