li2 is stable but be2 is not stable . explain<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The stability of diatomic molecules like Li\u2082 and Be\u2082 can be explained using molecular orbital (MO) theory, which describes how atomic orbitals combine to form molecular orbitals.<\/p>\n\n\n\n Lithium (Li\u2082):<\/strong><\/p>\n\n\n\n Each lithium atom has an electronic configuration of 1s\u00b2 2s\u00b9. When two lithium atoms bond to form Li\u2082, their atomic orbitals combine to form molecular orbitals. The bonding molecular orbitals (\u03c31s and \u03c32s) are filled with electrons, while the antibonding molecular orbitals (\u03c31s and \u03c3<\/em>2s) remain empty. This results in a bond order of 1, indicating a stable bond between the two lithium atoms. Additionally, all electrons in Li\u2082 are paired, making it a diamagnetic molecule.<\/p>\n\n\n\n Beryllium (Be\u2082):<\/strong><\/p>\n\n\n\n Each beryllium atom has an electronic configuration of 1s\u00b2 2s\u00b2. In the Be\u2082 molecule, the bonding molecular orbitals (\u03c31s and \u03c32s) are filled with electrons, and the antibonding molecular orbitals (\u03c31s and \u03c3<\/em>2s) are also filled. This results in a bond order of 0, indicating no net bonding interaction between the two beryllium atoms. Consequently, Be\u2082 does not form a stable molecule under normal conditions.<\/p>\n\n\n\n Conclusion:<\/strong><\/p>\n\n\n\n The key difference between Li\u2082 and Be\u2082 lies in their bond orders. Li\u2082 has a bond order of 1, signifying a stable bond, while Be\u2082 has a bond order of 0, indicating instability. This difference arises from the specific electron configurations and the resulting molecular orbital interactions in each molecule.<\/p>\n","protected":false},"excerpt":{"rendered":" li2 is stable but be2 is not stable . explain The Correct Answer and Explanation is : The stability of diatomic molecules like Li\u2082 and Be\u2082 can be explained using molecular orbital (MO) theory, which describes how atomic orbitals combine to form molecular orbitals.
