H- C- H
H
Explanation:
Lewis structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.
Carbon is an element which belong to group 14. Atomic number of carbon is 6 that means it contains 6 electrons, Thus the electronic configuration is represented as:
. Thus the valence electrons are 4.
Hydrogen is an element which belong to group 1. Atomic number of hydrogen is 1 that means it contains 1 electron, Thus the electronic configuration is represented as:
. Thus the valence electron are 1.
The four valence electrons of carbon are shared with one valence electron of hydrogen each.

Answer:
Cr3+ is green and V2+ is purple. Cr3+ and V2+ are both d3 so there can be a lot of movement between energy levels to produce colored light. Cd2+ and Hg2+ are both d10 (full d orbital, much less electron movement).
