Use the octet rule to predict the formula of the compound that would form between sulfur and hydrogen, if the molecule contains only one sulfur atom and only single bonds are formed. Formula:

Explanation / Answer

1)

Sulfur has 6 valence electrons

So, it needs 2 more electrons to complete its octet

So, it will form 2 covalent bonds

Answer: 2

2)

Since S forms 2 covalent bonds as explained above, it will bond with 2 hydrogen

the formula will be H2S

Answer: H2S
