Make Lewis Dot Structures for common ions:

Question

a. H¹⁺ b. Li¹⁺

c. Cl^1- d. O^2-

Answer 1

Cannot easily draw dot structures on this platform, but will describe them to you, so maybe you can draw them.

a) H has 1 valence electron. H⁺ has lost that electrons, so the dot structure for H⁺ is just [ H ]⁺ (no dots)

b) Li has 1 valence electrons. Li⁺ has lost 1 so has 0 left. Dot structure would be [Li ]⁺

c) Cl has 7 valence electrons. Cl- has gained 1 so now has 8. Dot structure is Cl with 2 dots on all four sides

d) O has 6 valence electrons. O^2- has gained 2 so how has 8. Dot structure is O with 2 dots on all four sides
