The atom
100
This is the number of protons in the nucleus of an atom of a given element, and is also the number of electrons surrounding the nucleus and is used to identify an element.
What is atomic number?
100
This is the part of a chemical reaction that hols its original elements before a reaction occurs.
What is reactants?
100
This is the ability to do work or supply heat.
What is energy?
100
This state of matter takes the shape of whatever container its in.
What is liquid?
100
This part of the atom holds the neutral and positive charges.
What is nucleus?
200
Elements in the same column, or groups, share similar of these.
What is properties?
200
In order to balance equations we use these to balance the elements on both sides of the equation.
What is coefficients?
200
This type of equation includes a heat change, negative or positive.
What is thermochemical equation?
200
How are particles in a solid matter packed.
What is tightly?
200
This is the smallest particle of an element.
What is atom?
300
This is the classification of the elements that touch the zig-zag line in the periodic table.
What is metalloids?
300
This law dictates that the quantity of each element does not change in a chemical reaction.
What is law of conservation of mass?
300
This is the amount of heat required to raise 1g of a substance by 1C.
What is specific heat?
300
These are the four states of matter.
What is solid, liquid, gas, and plasma?
300
Protons and neutrons make up most of the atoms what.
What is mass.
400
What is the most reactive element due to high electronegative.
What is fluorine?
400
This is a substance that speeds up a reaction without being used up by the reaction.
What is catalyst?
400
H is the change in this that accompanies the formation of one mole of a compound.
What is enthalpy?
400
Liquid turns into this when it is heated.
What is vapor?
400
These are found in discrete locations around the nucleus, which are found on shells.
What is electrons?
500
This periodic trend increases as you go down the periodic table and decreases as you go to the right of the periodic table.
What is atomic radius?
500
The ions that we eliminate are called these.
What is spectator ions?
500
This is an insulated device that is used to measure heat changes.
What is calorimeter?
500
This property does not depend on the amount of the matter present.
What is intensive?
500
This man fired alpha particles at gold foil and noticed that most passed through, but others were reflected.
What is Ernest Rutherford?
