Covalent bonding versus ionic bondingScience and Technology
When a two non-metal atoms share some electrons they form a covalent bond. However, when a metal and non-metal atoms interact, electron(s) is/are transferred from the metal atom to the non-metal atom to form an ionic bond. We can use quantum chemistry tool in Avisto to learn the differences between these two types of bonding.
For covalent bond: H2, Li2, and F2
For ionic bond: Li-F and NaCl
Examine the differences in atomic partial charges, dipole moments, and electrostatic potential surfaces of these molecule.
To use tools in Avisto: Download it Here
1. Using MolDesign to build these diatomic molecules.
2. Use Basic QChem Edu or Basic QChem tool to find the stable structures for these molecules.
3. View results in PsiViewer and report the results.
Example: H2 and Li-F
|Atomic partial charges||H1 = H2 = 0.0||Li = 0.77 and F = -0.77|
|Dipole moment (D)||0.0||5.28|
