Which way do periods move on the periodic table? period are vertical and go down
What kind of boundary moves towards each other? convergent
Which subatomic particle has a negative charge? electrons
What kind of boundary moves apart? divergent
What is energy with movement called? kinetic energy
Which subatomic particle has a positive charge protons
How does the Sun generate energy? nuclear fusion
Which subatomic particle has a neutral charge? neutrons
Which subatomic particles is similar in size? protons and neutrons
What is the proper way to light a bunsen burner? make sure air vent is closed, make sure needle valve is closed, turn on gas, turn needle half turn, striker, adjust height, let air in,
How do you find atomic mass in an atom? protons plus neutrons

Where are the most reactive metals on the periodic table, and what are they called? alkali metals
How many valence electrons do the most reactive types of elements have? 1 or 7
How many valence electrons do alkali metals have? Alkaline earth? 1 alkali metals and 2 for alkaline earth
How much larger is a centimeter than a millimeter? ten times larger
What is matter? objects that take up space and have a mass
What is a broad explanation that is widely accepted because it is backed up by a great deal of evidence? Theory
What is the equation for density? mass/volume
What is the equation for speed? distance/time
What kind of boundary is the San Andreas fault on? strike-slip, transform
Two nonmetals bonded together are what kind of compound? Covalent compound
If an atom has one valence electron, what would its charge be when it becomes an ion? -1
Where are the metalloids located? stair step between nonmetal and metal
What is the process of how the Earth was formed called? accreation
What are covalent bonds? share electrons, made of non-metals only
Know how to draw a proper Bohr Model
Know how to draw a proper Lewis Diagram
What is an inverse relationship? one one variable increases the other decreases
What is a direct relationship? one increase other increase, one decreases other decreases
What kind of object does not let electrons to flow through an object? insulator
