Web13 hours ago · CH4 is a nonpolar molecule as it has a symmetric tetrahedral geometrical shape with four identical C-H bonds. The electronegativity of carbon and hydrogen is 2.55 and 2.2, respectively, which causes the partial charges to be almost zero. The difference in electrostatic potential is also minimal giving an overall nonpolar molecule. WebNov 28, 2024 · C and H have very similar electronegativities, causing their bond to be considered a nonpolar covalent bond. The reason why they are so far apart is because of their difference in electrons in the valence shell. It makes more sense for H to be in group 1 because it was 1 electron in the valence shell, resulting in it being so far apart from C. Top green anoles food
