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
molecular covalent compound
network covalent compound
...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?
lines between the element symbols
...lists the atoms present in groups to indicate connectivity between them:
-does it convey information about the 3D shape of the compound?
condensed structural formula
no, only connectivity
...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)
NO nitric oxide
-binary nonmetal compounds containing only hydrogen and carbon:
-given special names, how are they named?
according to the number of carbon and hydrogen atoms in the formula
