The Periodic Table
100
Anything that has mass and takes up space.
What is matter?
100
Solids, liquids, and gases.
What are the states of matter?
100
A pure substance that cannot be separated into simpler substances by physical or chemical means.
What is an element?
100
The smallest particle into which an element can be divided and still be the same substance.
What is an atom?
100
A list of elements that are classified as metal, nonmetals, and metalloids according to their properties.
What is the periodic table?
200
The space taken up by an object.
What is volume?
200
State of matter that does not change shape and has particles that are close together.
What is a solid?
200
The three major categories of elements.
What are metals, nonmetals, and metalloids?
200
The center of an atom which contains protons and neutrons.
What is a nucleus?
200
A horizontal row on the periodic table.
What is a period.
300
The curve at a liquid's surface by which one measures the volume of the liquid.
What is meniscus?
300
State of matter that has a definite volume, but its shape may be different.
What is a liquid?
300
A pure substance composed of two or more elements that are chemically combined.
What is a compound?
300
Particles of the nucleus that have no electrical charge.
What are neutrons?
300
A vertical column of elements on the periodic table.
What is a group.
400
The formula for finding volume.
What is length x width x height?
400
The volume of the gas is inversely proportional to the pressure of a gas when temperature is constant.
What is Boyle's Law?
400
A combination of two or more substances that are not chemically combined.
What is a mixture?
400
A subatomic particle that has a negative charge.
What is an electron?
400
The most reactive group of metals on the periodic table because their atoms can easily give away the one outer-level electron.
What are alkali metals?
500
The tendency of an object to resist a change in motion.
What is inertia?
500
The volume of a gas is directly proportional to the temperature of a gas when pressure is constant.
What is Charles's Law?
500
A substance that is dissolved.
What is solute?
500
The number of protons in the nucleus of an atom.
What is the atomic number?
500
Very reactive nonmetals on the periodic table
What are halogens?
