solutions are much less high priced, yet strategies of determining the respond are effective. to discover the style of valence electrons in an atom of a definite element, you may desire to seek for suggestion from the periodic table. despite if the counsel does not inform you without delay what number electrons there are in the valence shell of an atom, you may desire to undergo in recommendations that factors are arranged in columns (communities) in accordance to the style of valence electrons. team one million factors, as an occasion, have only one valence electron. team 2 factors have 2 valence electrons. communities 3 via 12 variety between one and 2 because of the fact they're transition factors. team 13 factors have 3 valence electrons. team 14 factors have 4 valence electrons. team 15 factors have 5 valence electrons. team sixteen factors have six valence electrons. team 17 factors have 17 valence electrons, and team 18 factors (noble gases) have in maximum situations 8 valence electrons apart from helium that only has 2. Going back on your question, you may desire to learn the situation of each and every of the above factors in the periodic table and are available up with the likely answer. a. sodium - atomic style eleven - present day in team one million - one valence electron b. lithium - atomic style 3 - present day in team one million - one valence electron c. copper - atomic style 29 - present day in team eleven - transition element - one valence electron (despite in case you may no longer discover this counsel on the periodic table, undergo in recommendations that transition factors could have one or 2 valence electrons.) d. fluorine - atomic style 9 - present day in team 17 - seven valence electrons e. sulfur - atomic style sixteen - present day in team sixteen - six valence electrons answer: The element with the main important style of electrons in the outermost shell is "d. fluorine".
