poly atomic ion
|
charged group of covalently bonded atoms
|
|
|
formula unit
|
simplest collection of atoms from which one ionic compounds formula can be established
|
|
|
single bond
|
covalent bond produced by the sharing go one pair of electrons between 2 atoms
|
|
|
structural formula
|
indicates the kind, number, arrangement, and bonds but not the unshared pairs of the atoms in a molecule
|
|
|
lone pair
|
pair of electrons that is not involved in boning and that belongs exclusivley to one atom

|
|
electron dot notation
|
electron configuration notation in which only the valence electrons of an atom of a particular element shown, indicated by dots and placed around the atoms symbol.
|
|
|
octect rule
|
gaining or loosing or sharing electrons to have 8 in the highest energy level.
|
|
|
diatomic molecule
|
molecule containing 2 atoms
|
|
|
molecular formula
|
shows types and numbers of atoms combined in a single molecule of molecular formula
|
|
|
polar covalent bonds
|
bonded atoms have an unequal attraction for the shared electrons
|
|
|
non polar covalent bonds
|
bonding of electrons are equally shared by the bonded atoms, resulting in a balanced distribution of electron charge
|
|
|
covalent bonds
|
results from sharing electron pair b/w 2 atoms
|
|
|
ionic bond
|
the transfer of electrons from one atom to another
|
|
|
chemical bond
|
mutual electrical attraction b/w the nuclei and valence electrons of different atoms that bonds atoms together.
|
|
|
aufbau principle
|
the number of electrons in an atom is equal to the atomic number. the lowest orbitals are filled first
|
|
|
hunds principle
|
when filling sub levels, electrons are placed in individual orbitals before being paired up.
|
|
|
pauli exclusion
|
no two electrons in an atom have the same 4 quantum numbers.
