Chp. 6 vocab Flashcards
when a hydrogen atom that is bonded to a highly electronegative atom of a molecule is attracted to two unshared electrons of another molecule
Hydrogen Bonding
Force that attracts electrons from one atom to another, transforming neutral atoms into an ion
Ionic Bond
tendency of atoms to prefer to have eight electrons in valence shell
Octet rule
group of atoms that are held together by chemical forces; is smallest unit of matter that can exist by itself
Molecule
Chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms
Molecular formula
Covalent bond in which a pair of electrons shared by two atoms is held more closely by one atom
Polar covalent bond
the attractive force that holds atoms or ions together
Chemical Bond
A bond formed when atoms share one or more pairs of electrons
Covalent Bond
Bond formed by the attraction between positively charged metal ions and the electrons around them
Metallic Bond
Bond in which the bonding electrons are equally attracted to both bonded atoms
Nonpolar covalent bond
The collection of atoms corresponding to an ionic compound’s formula such that the molar mass of the compound is the same as the mass of 1 mol of formula units
Formula unit
Electron pair in the outermost shell of an atom that is not shared or bonded to another atom
Lone Pair/ Unshared Pair
Intermolecular attraction resulting from the uneven distribution of electrons and the creation of temporary dipoles
London Dispersion forces
The energy required to break the bonds in 1 mol of a chemical compound
Bond energy
Forces that exist between two molecules
Intermolecular Forces
