Atomic Bonding Flashcards
Cation
a positively charged ion, one that would be attracted to the cathode in electrolysis.
Structural Formula
a formula which shows the arrangement of atoms in the molecule of a compound.
Ionic bond
when a positively charged ion forms a bond with a negatively charged ions and one atom transfers electrons to another.
Nonpolar covalent bond
a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule
Crystal lattice
the symmetrical three-dimensional arrangement of atoms inside a crystal.
Chemical bond
chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic forces.
Polar covalent bond
a type of chemical bond where a pair of electrons is unequally shared between two atoms
Lewis structure
diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
Covalent bond
a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Polyatomic ion
a charged chemical species (ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.
Oxidation number
the charge that atom would have if the compound was composed of ions.
Ionic compound
a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.
Formula unit
the chemical formula with the least number of elements out of the set of empirical formulas having the same proportion of ions as elements:
Anion
a negatively charged ion, as one attracted to the anode in electrolysis.
Molecule
the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
