oxidation #
|
the charge on an ion
|
|
|
hydrate
|
a compound that has water chemically attactched to its ions and written into its chemical formula
|
|
|
molecule
|
a neutral particle that forms from a result of electron sharing
|
|
|
binary compound
|
compound that is composed of two elements
|
|
|
chemical formula
|
tells what elements a comound contaions and the exact # of the atoms of each element in a unit of that comound
|
|
|
chemical bond
|
the force that holds atoms together in a comound
|
|
|
How do you correctly write the formula for a hydrate?
|
write formula 4 comound, place dot followed by # of water molecules (CuSO4 . 5H2O)
|
|
|
What elements bond ionically, and what elements bond covalently? Why?
|
ionically: nonmetals, and metals or metalliods
covalently: between at least 2 nonmetals why? |
|
|
What information does an oxidation number give you? Why don’t you use oxidation numbers for covalent bonds?
|
it tells you how many electrons an atom has gained lots or shared. Becuase it has to do with gaining and loses electrons which covalent bonds don't do.
|

Be able to choose, draw, and explain how elements can form covalent bonds
|
see differences sheet
|
|
|
Can Oxygen bond with itself? Why or why not, and what type of bond is this?
|
yes, they can make a covalent bond because they can share their two unpaired electrons to fill the outer layer
|
|
|
How do you write the formula for a binary compound formed ionically?
|
1)write symbol of element w/ a + exidation number or charge
2) write symbol of element w/ - oxidation number 3) charges must balence(cross method) |
|
|
How do you write the name for a binary ionic compound?
|
1)write name of + ion
2) If + ion can form more than 1 oxidation #, determine oxidation # from formula and wrte in roman numerals, if not, step 3 3)write root name of - ion, 4) add ide |
