Giving max amount of points, I just need this answered. It's a K12 assignment. Using the room temperature line (orange line) and
your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. Explain your answers.
Please help. I know someone out there has a graph and has probably done this. :( I have like 50 minutes and this is the last question.

Answer:
bond angle = 120 °
Explanation:
Lewis structure is used to represent the arrangement of the electrons around the atom in a molecule. The electrons are shown by dots and the bonding electrons are shown by line between the two atoms.
For ,
The number of valence electrons = = 6
The skeleton structure of the compound is in which one C molecule act as a central atom and is bonded to the three H with one sigma bond each.
Number of valence electrons used in skeletal structure = 6
So,
Remaining valence electrons = 0
The Lewis structure of the compound is shown below:
H
:
C⁺
: :
H H
<u>The geometry is trigonal planar which has an angle of 120 °.</u>
