What types of bonds are there?
There are 3 main types of bonds; Binary, Ternary, and covalent a.k.a molecular
Binary- is between 2 elements one metal(yellow) and non-metal(blue)
Example- sodium chloride. You change the second elements to -ide
Ternary- is between any element metal or non-metal and one poly-atomic
Example- Sodium Carbonate
Covalent- is between two non-metal(blue)
Example- carbon sulfur
Ionic Compounds (criss-cross)
We do not know the charges on transition metals, so we use roman numerals to tell us.
Fe(ll) this means that iron has a positive one two charge. When we pair it with a non-transition metal, we have to criss cross, Fe(ll) and phosphorus, Iron (ll) Phosphide
Acids and Bases
elements with the ending -ide
¨my ride has hydrolics¨
add the elements in hydro_____ic acid
Example hydrochloric acid
elements ending ind -ate (polyatomics)
"i ate something icky"
add the elements into _______ic
carbnate
carbonic acid
elements ending with -ite
¨sprite is delicious¨
