Unit 4 Bonding
Bonding Vocabulary
| Term | Definition |
|---|---|
| adhesion | the tendency of molecules to stick to substances that are dissimilar |
| anion | a negatively charged ion |
| cation | a positively charged ion |
| chemical bond | an electrical interaction between the positively charged nuclei and the negatively charged electrons of atoms that forms when the force of attraction is stronger than the force of repulsion |
| cohesion | the action or property of like molecules sticking together, being mutually attractive |
| covalent bond | a bond in which pairs of electrons are shared between atoms, instead of being transferred from one atom to another |
| double covalent bond | a bond in which atoms share two pairs of electrons |
| electronegativity | the ability of an atom to attract additional electrons |
| electrostatic force | a force in which oppositely charged particles are attracted to each other, while like charges repel each other |
| intermolecular forces | the attractive forces acting between molecules |
| intramolecular bond | a bond that is occuring within a molecule |
| ion | an atom with a positive or negative charge |
| ionic bond | a bond that occurs between atoms, through the transfer of electrons, when a positively charged atom and negatively charged atom are attracted to one another |
| molecule | a group of atoms that have chemically bonded and behave as an individual unit |
| nonpolar covalent bond | a bond that forms between atoms in which their electrons are shared equally |
| octet rule | when an ion or an atom has eight valence electrons, it is at its most stable electron configuration |
| polar covalent bond | a bond in which electrons are shared unequally between atoms |
| single covalent bond | a bond in which atoms share only one pair of electrons |
| triple covalent bond | A bond in which atoms share three pairs of electrons |
| valence electrons | the electrons found in the outermost electron shell of an atom |
