Table 1. Compatibility of even-odd rule with Lewis-octet rule. Names, formulas and structural formulas of uncharg- ed single-bonded molecules are classified by the atoms num- ber. All molecules, stable in the gas phase, are composed of atoms from the main group of elements and are interconnected to each of their first neighbor by only one covalent bond. All left side numbers come from Mendeleev pe- riodic table and all right side numbers are equal to eight except for hydrogen with a left-side number of 2 according to Lewis-octet rule. |
| Table 2. Molecules following only the even-odd rule. Names, formulas and structural formulas of uncharged single-bonded molecules are classified by the atoms number. All molecules are stable in the gas phase and all atoms belong to the main group of elements and are interconnected to each of their first neighbor by only one covalent bond. All left side numbers originate from Mendeleev periodic table and are from 1 for Lithium (Li) to 8 for Xenon (Xe) and right side numbers from 2 to 14, are calculated using the even-odd rule defined above. | ||
