Here's why:
* Chemical Formula: The formula for methane is CH₄. This means it has one carbon atom (C) and four hydrogen atoms (H).
* Nomenclature: The term "tetrahydride" implies four hydrogen ions (H⁻). This isn't accurate for methane because the hydrogen atoms are covalently bonded to the carbon atom, meaning they share electrons.
