Bond between two ions (metal and nonmetal)(Cation and anion)
Gives actual number of atoms of each element in a molecule of a compound. (ie H
Relative number of atoms of each element of the compound. (ie. NaCl,H
Uses lines to show bonds between atoms.
Those that exist in nature with single atoms as their basic units
Do not usually exist in nature with single atoms as basic units. ie. O
2 or more covalently bonded NONMETALS
Composed of more than two ions
1 nonmetal - 1 metal
Must be charge neutral
Always a positive and negative ions
2 elements (cation and anion)
Affect Ozone Layer
Contain only single bonds
Contain double bonds
Contain Triple Bonds
Carbon can join to itself
Contain only Hydrogen and Carbon (Usually used as fuels)
Made Urea from inorganic chemistry
Conatin more than just Hydrogen and Carbon, such as alcohols.
Substance present in lesser amount (ie. Salt)
Substance present in greater amount (ie water)
Conduct electricity, no ions in solution.
Substance dissovled completely in solution
HCl - also strong electrolyte
Also weak electrolyte
Solid forms from 2 solutions
Shows complete neutral formulas for every compound
Complete Ionic Equation
Shows charges of all compounds in reaction
Net Ionic Equation
Shows only charges and ions of compounds that change throughout the reaction.
Do not affect reaction
Acid produces hydrogen ions
Base produces hydroxide ions
Acid Base reactions always form...
SALT and WATER
