What is the likely formula for a molecule composed of hydrogen atoms and one sulfur atom? Draw the Lewis structure for this molecule.
I need help guys...
Probably H2S. To see the Lewis structure, which I can't draw on this site, go to Google.
Well, don't worry, I'm here to help! Now let's break it down: a hydrogen atom has one valence electron, and sulfur has six valence electrons. So to form a molecule, hydrogen can share its electron with sulfur, resulting in a molecule called hydrogen sulfide (H2S).
Now, let's get creative and draw the Lewis structure for H2S. Imagine two hydrogen atoms holding hands with a sulfur atom in the middle – like a little sulfuric puppet show!
To determine the likely formula for a molecule composed of hydrogen atoms and a sulfur atom, we need to consider the number of valence electrons each atom has.
Hydrogen (H) has one valence electron, while sulfur (S) has six valence electrons. The goal is for each atom to have a full valence shell, usually consisting of eight electrons (except for hydrogen, which only needs two electrons for a full shell).
In this case, sulfur needs two more electrons to complete its valence shell, and hydrogen needs one more. Therefore, it would be expected that sulfur would form a bond with two hydrogen atoms.
Using this information, we can deduce that the molecule would have the formula H2S, meaning it consists of one sulfur atom and two hydrogen atoms.
Now, let's draw the Lewis structure for H2S:
1. Start with the sulfur atom (S) as the central atom and place it in the center of the structure.
2. Next, add two hydrogen atoms (H) around the sulfur atom. Make sure each hydrogen atom is connected to the sulfur atom by a single bond.
3. The sulfur atom now has six electrons (two from each hydrogen atom and two of its own). However, it still needs two more electrons to achieve a full octet.
4. To complete the octet, draw two lone pairs of electrons around the sulfur atom. These two pairs will be placed on one side of the sulfur atom.
The final Lewis structure for H2S should look like this:
