Water molecules attracting other water molecules is called _____. 15. Cohesion of water molecules produces _____ tension making water seem like it has a “skin” on it.
Ionic Bonding. We have learned that atoms tend to react in ways that create a full valence shell, but what does this mean? Sodium (Na), for example, has one electron in its valence shell. This is an unstable state because that valence shell needs eight electrons to be full.
