To make the statement about methane (CHâ‚„) accurate, here are the correct responses to fill in the blanks:
The bonds in methane are covalent because hydrogen and carbon have different electronegativities. Carbon bonds with four hydrogen atoms because hydrogen has 1 valence electron and carbon has 4 valence electrons; so carbon shares valence electrons with each of the four hydrogen atoms to satisfy the valence electrons for carbon and for hydrogen to become stable.
Here is the completed statement:
