Term | Definition |
Ionic Bonding | Chemical bonding that results from the electrical attraction between cations and anions |
Covalent Bonding | results from the sharing of electron pairs between two atoms |
Electronegitivity nonpolar-covalent | 0-0.3 |
Electronegitivity polar-covalent | 0.4-1.7 |
Electronegitivity ionic | >1.7 |
VSEPR theory | predicts the shape of some molecules and assumes that pairs of valence electrons surrounding an atom repel each other |
What atom goes in the middle in a 3 atom compound? | Carbon or the least electronegitive atom |
Hydrogen Bonding | The intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom isattracted to an unshared pair of electrons of an electronegative atom in a nearby molecule |
