Atomic mass is a combination of what two subatomic particles?
What are protons and neutrons
200
Two or more substances that are mixed together but NOT chemically joined
What is a mixture
200

What is Chemical Formula
200
I am shiny, ductile, malleable and found on the left side of the stair-step. What am I?
Metal
300
Where are electrons located?
Electrons are located on the electron shells (also called energy levels or orbitals) - OUTSIDE of the nucleus.
300
Elements in the same PERIOD have the same number of ?
What is electron shells (energy levels / orbitals)
300
Two or more atoms of the SAME element chemically bonded together
What is Element Molecule
300
A _____________ is the small number following a symbol that shows how many atoms of ONLY THAT element are in the compound.
What is subscript
300
I am a brittle and dull non-metal. Where am I located on the periodic table?
Right of the stair-step.

Which subatomic particle(s) are used to find charge?
What are protons (positive) and electrons (negative)
400
Elements in the same GROUP have the same number of ?
What is valence electrons (electrons on the outermost energy shell). Look at the number next to the "A" at the top of the column on the Periodic Table.
400
Two or more atoms of DIFFERENT elements chemically bonded together
What is Compound Molecule
400
The _______________ at the beginning of a chemical formula changes the number of molecules that are required for a chemical reaction.
What is coefficient (To determine the number of atoms for each element, multiply the coefficient by each subscript.)
400
Substances that exist before the reaction occurs
What is Reactant (left side of chemical equation)
500
Which subatomic particle(s) are used to find mass?
What are proton (1 amu) and neutrons (1 amu). Both located in the nucleus. All the mass of the atom is found in the nucleus.
500
The Periodic Table is organized by ?
What is atomic number (increases to the right and down)
500
Consists of two or more atoms chemically bonded together
What is Molecule
500
This combines chemical formulas to show us which substances react and which substances are formed in a chemical reaction.
What is Chemical Equation
500
According to this law, you must have the SAME number of atoms of each element before the reaction begins AND after the reaction begins. You also must start and end with the SAME ELEMENTS.
