bonds
covalent bonding
also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms
what is a reactant?
substance that takes part in and undergoes change during a reaction
what is a physical property?
any property that is measurable, whose value describes a state of a physical system
what is a chemical structure in chemistry?
a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid.
triple covalent bond
chemical bond between two atoms involving six bonding electrons
what is a decomposition reaction?
a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds
any of a material's properties that becomes evident during, or after, a chemical reaction
chemical property
a central atom bonded to three other atoms or groups
trigonal planer structure
metallic bond
bonds formed from the attraction between mobile electrons and fixed, positively charged metallic atoms
a reaction where two or more elements or compounds (reactants) combine to form a single compound
combination reaction
has the same uniform appearance and composition throughout
homogeneous mixture
difference between linear and planar?
linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond-angle of 180.
this molecule is made up of 3 equally spaced sp2 hybrid orbitals arranged at 120o angles. The shape of the orbitals is planar triangular
two pairs of electrons are shared between the atoms rather than just one pair
double covalent bond
type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound
single replacement reaction
what is a intensive property?
a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system
molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron
tetrahedral strucutre
when only one pair of electrons is shared between atoms
single covalent bond
type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
double replacement reaction
simply any mixture that is not uniform in composition
Herterogeneous
Linked representations are normally called lists while sequential representations are called arrays
Linear structure
