Re: AXE Formation Post by Chiara R 1K » Fri Oct 23, 2015 3:57 am To get the AXE notation, A is representative of the central atom, X represents the number of atoms bonded to the central atom (the subscript is the number of non-central atoms), and E represents the number of lone pairs on the central atom. of electrons which are alone that is the lone pairs around the atom minus half the number of electrons in bonds. A = Central atom. View Live. Based on the Lewis structure above the AXE notation would be AX 4 E 0, meaning there are a total of four substituents (4 atoms and 0 lone pair) coming off of the central atom. Paragraph Ethylene serves as a hormone in plants. Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP).
