draw Lewis Structures for the following FIVE elements.
H2S
CH2Cl2
NH3
C2H6
CH3OH
Dang, I do not think its possible to draw it on this website and post it for you to view. Maybe you should try searching it on the internet (google).
could you give me a link to some of them

Draw the lewis structures for H2S,CH2CI2,NH3,and c2h6.
I don't get it
To draw Lewis structures for the given molecules, follow these steps:
1. Calculate the total number of valence electrons for each atom in the molecule.
- Hydrogen (H) has 1 valence electron.
- Carbon (C) has 4 valence electrons.
- Nitrogen (N) has 5 valence electrons.
- Oxygen (O) has 6 valence electrons.
- Sulfur (S) has 6 valence electrons.
- Chlorine (Cl) has 7 valence electrons.
2. Determine the central atom in the molecule. The central atom is usually the least electronegative or the only non-hydrogen atom.
Now, let's draw the Lewis structures for each molecule:
1. H2S (Hydrogen sulfide):
- Hydrogen (H) atoms share one electron each with the sulfur (S) atom to form a single covalent bond.
- The Sulfur atom has six valence electrons, but after bonding with two hydrogen atoms, it shares a total of eight electrons (full octet).
H:S:H
2. CH2Cl2 (Dichloromethane):
- Carbon (C) is the central atom.
- Carbon forms single covalent bonds with two hydrogen (H) atoms and double bonds with two chlorine (Cl) atoms.
- Each hydrogen atom contributes one electron, each chlorine atom contributes seven electrons, and carbon contributes four electrons.
- Carbon shares four electrons with the hydrogen atoms and eight electrons with the chlorine atoms.
- Place the remaining electrons around the atoms to fulfill the octets (except for hydrogen).
H:C(Cl):C(Cl):H
3. NH3 (Ammonia):
- Nitrogen (N) is the central atom.
- Nitrogen forms a single covalent bond with three hydrogen (H) atoms.
- Each hydrogen atom contributes one electron, and nitrogen contributes five electrons.
- Nitrogen shares three electrons with the hydrogen atoms.
- Place the remaining two electrons on the nitrogen atom as a lone pair.

4. C2H6 (Ethane):
- Carbon (C) is the central atom.
- Each carbon atom forms single covalent bonds with three hydrogen (H) atoms.
- Each carbon atom contributes four electrons, and each hydrogen atom contributes one electron.
- Carbon shares four electrons with the hydrogen atoms for each carbon atom.

5. CH3OH (Methanol):
- Carbon (C) is the central atom.
- Carbon forms single covalent bonds with three hydrogen (H) atoms and a single covalent bond with an oxygen (O) atom.
- Each hydrogen atom contributes one electron, oxygen contributes six electrons, and carbon contributes four electrons.
- Carbon shares four electrons with the hydrogen atoms and shares two electrons with the oxygen atom.
- The oxygen atom shares two electrons with the carbon atom and has two lone pairs.
