CHEM CH2-3

and are:
of a class of compounds called:

same molecular formula, different structures

2 types of covalent compounds:

atoms of different elements held together by covalent bonds

-compound of individual covalently bonded molecules
-three dimentional network of atoms held together by covalent bonds

...contains the symbol for each element present and a subscript number to identify the number of atoms of each element in the molecule

...shows the simplest whole-number ratio of elements in a compound:

network covalent compounds are represented using..

...shows linkages of all atoms in the molecule

how are covalent bonds represented in a structural formula?

...lists the atoms present in groups to indicate connectivity between them:
-does it convey information about the 3D shape of the compound?

...two dimentional representation of a 3D structure that can be easily drawn on paper:
-bonds that lie in the plane of the paper are represented by:
-bonds that lie in front of the plane of the paper:
-bonds that lie behind the plane of the paper

...interpenetrating spheres represent the relative amount of space occupied by each atom in the molecule:

two common classes of covalent compounds:
-can a compound belong to more than one catagory?

...consist of 2 elements, both nonmetals

Prefixes used in naming Binary Nonmetal Compounds:

common old names for some binary nonmetal compounds:(6)

-binary nonmetal compounds containing only hydrogen and carbon:
-given special names, how are they named?
