Are the Carbon atoms full though. I don't know. My teacher was saying something about putting the atoms with dots on a diagonal and she said something about using arrows to indicate the "CC" bonds.
???????????????????????????????????????
I don't understand what you mean by th .. are next to the two C atoms.
Sorry. You are right. I got so carried away trying to space everything properly I didn't count the H atoms. Just remove the two H atoms and the 4 dots on the bottom. I'll redraw it it necessary.
my teacher said the same
There should only be 4 hydrogens in C2H4
Usually a BAR (as in -) is used to show a bond and a bar can be replaced with two .. for two electrons for the electron dot structure.
   H    H
   |    |
H-C=C-H
This is the "stick" model in which the - or | represents the bond between C and C and C and H. To make the electron dot structure, simply replace the | or - with .. or :
In C2H4 there is a double bond between C and C so I drew it as C=C. It can be represented as C::C also.
Are the carbon atoms full, though? yes. We should have a total of how many electrons?
For C2H4 we have
2C = 2 x 4 e each = 8 electrons.
4H = 4 x 1 e each = 4 electrons.
A total of 12 electrons.
Count each - or | as two electrons. You will count 12.
Obviously C2H4 should have been C2H4
Almost. On the bottom, interchange the .. and the H so the H atoms are on the bottom and the .. are next to the two C atoms.

See how this looks.
Draw the electron-dot structure and stuctural formulas for:
C2H4 (Dicarbon Tetrahydride)
hullo
soo silly
To draw the electron-dot structure for C2H4, also known as ethene or ethylene, follow these steps:
1. Start by placing the two carbon atoms in the center.
2. Carbon typically forms four bonds, so draw two lines (or a double bond) between the carbon atoms to represent their connection.
3. Next, place the four hydrogen atoms around the carbon atoms. Each hydrogen atom should have a single bond (represented by a line) with one of the carbon atoms.
4. To represent the electrons in the outer shells of the atoms, draw dots around each atom. Carbon has four valence electrons, so it should have four dots. Hydrogen has one valence electron, so it should have one dot.
Here is the electron-dot structure for C2H4:
```
H H
. .
H :C::C H
. .
H H
```
Alternatively, you can also use the lines and dots notation for the electron-dot structure. In this notation, the lines represent the bonds, and the dots represent the electrons.
The structural formula for C2H4 can be represented as:
H-C=C-H
In this formula, the lines represent the bonds, and the atoms are arranged in the order of carbon, carbon, hydrogen, hydrogen.
I hope this helps!
