The second element in a molecular formula usually ends with an "-ide".
Prefixes denote the quantity of each element in the molecule:
Di- = two
Mono- = one (used only when there is no prefix for the first element)
Examples and Applications
When naming compounds, if the first element is present in a quantity of one, it is typically just named without a prefix.
As molecular structures become more complicated, alternative strategies may have to be applied for accurate naming.
Valence Electrons and Formal Charge
Hydrogen Case Study
Valence Electrons of Hydrogen:
Hydrogen has one valence electron, which corresponds to its position in Group 1 of the periodic table.
In a neutral state, hydrogen has one electron.
Calculating Formal Charge:
To find the formal charge of hydrogen, you can use the formula:[ \text{Formal Charge} = \text{Valence Electrons} - \text{Non-Bonding Electrons} - \frac{1}{2} \text{Bonding Electrons} ]
