WebVSEPR uses the steric number and distribution of X's and E's to predict molecular geometric shapes. AXE method: The A represents the central atom; the X represents the number of sigma bonds between the central atoms and outside atoms; and the E represents the number of lone electron pairs surrounding the central atom. WebSubtract the steric number from the number of single bonds present around the central atom. This number represents the number of lone electron pairs in the molecule. Determine the geometry of the electron. Example: Electron Geometry of CH4 The molecule’s central atom is denoted by the letter C. The number of valence electrons in C is equal to four.
