What physical property of an element determines whether it acquires a positive or negative partial charge when participating in a polar covalent bond?

nature of atoms and molecules, focusing on the structure of the atom and how it was discovered. We next explore the various ways that atoms combine with other atoms to create molecules, looking at the different types of chemical bonds between atoms, how these bonds form, and how they determine the structures of molecules. We end with an examination of the water molecule and the properties that make it a crucial component of living organisms and their environment.
