Understanding Methane and Compounds

The video tutorial explores whether methane is an element or a compound. It explains that methane, with the chemical formula CH4, is a compound because it consists of more than one type of atom, specifically carbon and hydrogen. The video clarifies that methane is not found on the periodic table, which only lists elements, not compounds. It further discusses how atoms in methane are chemically bonded, using a molecular model to illustrate the bonds between carbon and hydrogen. The tutorial concludes by reiterating that methane is a compound due to its composition of different atoms.
