Chemistry Vocabulary?

Question

So, when I look up the chemistry vocabulary, I usually end up having to to look up a definition for every single word, because I don't understand the explanation of it. Then, I don't understand the definition of the definition, so I look up the definition of the definition of the definition, etc. Before I know it, I have entered a scary jungle of definitions, and it's really sad, and everybody cries.

So, if anyone has a 'simpler' chemistry vocabulary that they would like to share with me, that would be great!

I need a definition of the following words:
Acid, Indicator, Antioxidant, Ion, Balanced Chemical Equation, Metal, Base, Mixture, Catalyst, Non-metal, Chemical, Ph, Chemical Change, Physical Property, Chemical Formula, Polyatomic Ion, Chemical Property, Precipitate, Collison Model, Product, Combustions, Pure Substance, Compound, Reactant, Concentration, Salt, Decomposition Reaction, Temperature, Dissociate, Valence Level, Element, Enzyme.

Answer 1

I know most of them so I'll write down the easier and less basic ones.



Acid: A substance that conducts electricity, tastes sour and neutralizes bases.



Indicator: A test that determines if a substance is acidic or basic have the strenght of the acid or the base.



Ion: An atom that has either a positive or negative charge.



Balanced Chemical Equation: A skeleton equation that has the same amount of atoms on both sides.



Base: a substance that conducts electricity and neutralizes acids.



Precipitate: When a solid forms in a liquid.



Valence: The last energy level in an atom.



Product: What's on the right side of a chemical equation.



Compound: When two or more elements bond.



Reactant: What is on the left side of a chemical equation.



Polyatomic Ion: When two or more elements react as one ion.



Sorry for the lack of words I made them as simple as I could if you have anymore questions post them.
