Answer 2

Answer:

(i) S and S2– The number of valence electrons in sulphur is 6. The Lewis dot symbol of sulphur (S) is  .  The dinegative charge infers that there will be two electrons more in addition to the six valence electrons.Hence, the Lewis dot symbol of S2– is .  (ii) Al and Al3+ The number of valence electrons in aluminium is 3. The Lewis dot symbol of aluminium (Al) is . The tripositive charge on a species infers that it has donated its three electrons. Hence, the Lewis dot symbol is .  (iii) H and H– The number of valence electrons in hydrogen is 1. The Lewis dot symbol of hydrogen (H) is . The uninegative charge infers that there will be one electron more in addition to the one valence electron. Hence, the Lewis dot symbol is . Read more on Sarthaks.com - https://www.sarthaks.com/8308/write-lewis-symbols-for-the-following-atoms-and-ions-s-and-s2-al-and-al3-h-and-h
