This is the charge when an atom gains electrons and loses electrons.
What is negative when gains, positive when loses?
200
This scientist used Gold foil in his experiments. This scientist first introduced that atoms combine in specific ratios. This scientist said elements spontaneously emit radiation. This scientist said that the atomic model contained a sphere of pos and neg charged electrons.
Who is Rutherford, Dalton, Curie, and Thomson?

This speeds up a chemical reaction and this slows down a chemical reaction.
What is a catalyst and what is an inhibitor? ( The speeding up of a reaction in a living thing is with enzymes!)
300
This is the number above and below an individual element on the periodic table and the one that is the electrons and protons.
What is the atomic number (above), mass number (below) and the protons and electrons are the atomic number?
300
This is the definition of the law of conservation of mass.
What is the mass of the products in a chemical reaction are always equal to the mass of the reactants before and after the chemical reaction has occurred?
300
This is the left side of a chemical equation, the right side of a chemical equation, and the arrow within the equation.
What is reactants, products and yields?
300
These are the 4 different molecular models.
What are: dot diagrams, structural formula, ball and stick model, space filled model?
400
This is the number of dots on the electron dot diagram for:
P, Cl, Ca, Al, Li.
What is 5, 7, 2, 3, and 1?

This happens when thermal energy is added or removed from an object.
What is a change of state: solid --> liquid --> gas or reverse?
400
This is the reason why water is a covalent bond and polar between H and O.
What is water is 2 nonmetal atoms which share electrons forming a molecule are the reasons why it is covalent, the valence electrons shared unequally are the reason it is polar?
400
These are the big numbers before a compound in a chemical equation and these are the smaller numbers at the end of a compound on a chemical equation.
What are coefficients and subscript numbers that are included in a chemical formula?
400
This is the difference between endothermic and exothermic reaction.
What is endothermic reactions absorb more energy than they release and exothermic reactions release more energy than they absorb?
500
This scientist discovered radiation while working with minerals and thought that sunlight was necessary for minerals to give off energy that passed through paper, and the French chemist who did experiments on the law of conservation of mass.
Who is Becquerel, Lavoisier?
500
This is how you know a physical property of a substance is ionic or covalent.
What is a covalent cmpd would be liq/gas at room temp and an ionic cmpd would be a solid at room temp with a high melting point?
500
Explain the parts of the atom: particles, charges and describe "cloud" that is around it.
What is proton = positive, neutron = neutral, electron = negative: cloud is electrons rotating around nucleus?
500
In terms of surface area, this is why a large ship is able to float on water.
What is due to the large wide bottom of the boat there is greater surface area to contact with water, the force over a larger area = pressure against the water = boat floats?
500
This is how you can determine the rate of a chemical reaction.
What is you measure how quick reactants disappear or how quick products appear?
