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 |
