what do oxidation numbers represent?
Oxidation numbers represent the numbers of electrons an atom in a compound must gain or lose to return to its natural state.
-negative- that atom has gained that many negativity charged electrons.+positive- the atoms have given up that many.
how do you find oxidation numbers?
if one rule contradicts another, the first in the list should be followed. (example: Na2O, A sodium always has an oxidation number of +1. Oxygen is normally -2. 2(Na’s ON)+(O’s ON)=O 2(+1)+(-2)=O)

what is the crisscross method?
The crisscross method is a technique used in chemistry to determine the formula of ionic compounds by using the charges of ions.
What do the subscripts (e.g.the 2 in H2O) represent in a formula?
The number of atoms of that element in the molecule.
what is oxidation rule 2 ?
#2 the ion rule: the oxidation number of a monatomic number ion is equal to the change of the ion.
polyatomic ion compounds. Define...
Polyatomic ion compounds are ionic substances containing a group of covalently bonded atoms that act as a single, charged unit.

What is the "Don Juan Syndrome"?
The pattern of injuries resulting from jumping from a high place, landing on the feet, and fracturing the calcaneus, ankles, tib/fib, and potentially the lumbar spine.
What is the name of the organization that sets the standardized rules for chemical naming?
IUPAC (International Union of Pure and Applied Chemistry).
numero 4 oxidation rule..?
#4 the specific number oxidation rule: certain elements regularly have the same oxidation number compounds. A Alkali metals always have +1, B Alkaline earth metals always have +2, C hydrogen usually have +1, D oxygen usually have -1
what is a binary ionic compound?
Binary ionic compounds are chemical compounds consisting of only two different elements—a metal (cation) and a non-metal (anion).
Why do hypoglycemia and acute ischemic stroke often present with identical symptoms (slurred speech, one-sided weakness)?
Both conditions deprive the brain of essential "fuel"—the brain requires a constant supply of both oxygen (blocked in stroke) and glucose (low in hypoglycemia) to function.
