100
These are the most basic, pure substances found on earth
What is elements?
100
The chemical bond formed when two atoms share electrons.
What is a covalent bond?
100
These store energy used by cells.
What is a carbohydrate?
100
These have a lower pH and can be corrosive.
What are acids?
100
The positively charged part of the atom.
What is the proton?
200
When you have two or more elements
What is a compound?
200
A substance that resists changes in pH
What is a buffer?
200
Large, organic compounds made mostly of carbon and hydrogen. Examples include fats and oils.
What is a lipid?
200
These tend to have a higher pH, used in cleaning products frequently and can neutralize an acid.
What is a base?
200
The outer electrons found in an atom.
What are valence electrons?
300
When two or more things are combined but do not lose their chemical properties.
What is a mixture?
300
The chemical bond formed by the attractive forces between two ions of opposite charge.
What is an ionic bond?
300
This macro molecule provides structure to tissue and organs and helps carry out metabolism.
What is protein?
300
When two or more things combine and completely change their chemical make up.
What is a solution?
300
An atom or group of atoms that gain or lose electrons.
What is an ion?
400
Extremely small particles with unique attributes that make up the visible elements around us.
What are atoms?
400
The elements or compounds present at the beginning of a reaction.
What are reactants?
400
These are the building blocks of protein.
What are amino acids?
400
When two or more things become one.
What is synthesis?
400
When a molecule has a positive charge on one end, and a negative charge on the other.
What is a dipole?
500
The negatively charged part of an atom.
What is the electron?
500
The element or compound left over at the end of a reaction.
What is a product?
500
Carbon, Hydrogen, Oxygen and Nitrogen
What is the four elements that make up most of living matter?
500
When one thing breaks up into two or more things?
What is decomposition?
