Atomic Structure
This model of the atom depicts electrons in energy levels around the nucleus
What is the Bohr Model?
The number of protons in an atom determines this number on the periodic table.
What is the atomic number?
This type of calculation involves converting grams of a substance to moles
What is a mole conversion?
This piece of equipment is used to rinse chemicals from the eyes in case of exposure.
What is an eye wash station?
This type of reaction involves the breakdown of hydrogen peroxide into water and oxygen

The specific arrangement of electrons among the various orbitals is an atom is known as its electron what?
What is the electron configuration?
This is the total number of protons and neutrons in the nucleus
What is the mass number?
When calculating stoichiometry, this is the first step you should take
What is balancing the chemical equation?
You should always do this before starting any experiment in the lab
What is read and understand the lab instructions?
When vinegar reacts with baking soda, a gas is produced.
What is a chemical change?
The uncharged particle is found in the nucleus.
What is a neutron?
These elements, found in the center of the periodic table in groups 3-12, are known for their ability to conduct electricity and heat
What are the transition metals?
when given the mass of a reactant, this is the first step in finding the mass of the product

What is to alert others and clean it up immediately?
Burning wood is an example of this kind of reaction that gives off heat and light
What is combustion?
This model of the atom describes electrons in terms of probabilities rather than fixed orbits
What is the quantum mechanical model?
Members of this group, found in the s-block and characterized by having a single valence electrons, are known for their softness and vigorous reactions with water
What are the alkali metals?
This law states that equal volumes of gases, at the same temperature and pressure, contain the same number of molecules
What is Avogadro's law?
This is important to follow to ensure experiments are conducted safely
What are the lab protocols?
This word means that stuff you start with in a chemical reaction
What are the reactants?
This is the smallest unit of an element that retains the properties of that element
What is an atom?
Group 17 of the periodic table is known for its elements having seven valence electrons an high reactivity.
What are the halogens?
This type of reaction involves the combination of two or more substances to form a single product
What is a synthesis reaction?
This is the proper way to handle glassware
What is to check for cracks or chips before use?
The arrow in a chemical equation means this word
