What's the Matter?
This is the name for the three basic forms in which matter exists
What are solids, liquids, and gases?
This particle has a positive charge.
What is a proton?
This number tells you how many protons are in an atom.
What is the atomic number?
This is a pure substance made of only one kind of atom
What is an element?
You subtract the atomic number from the atomic mass to find this
What is the number of neutrons?
This state of matter has a definite shape and definite volume.
What is a solid?
This particle has no charge.
What is a neutron?
This is the vertical column on the periodic table where elements with similar properties are found
What is a group (or family)?
This is a substance made of two or more elements chemically combined.
What is a compound?
Oxygen has an atomic number of 8 and atomic mass of 16. It has this many neutrons
What is 8?
In this state, particles spread out and move freely.
What is a gas?
This particle has a negative charge.
What is an electron?
This scientist is credited with creating the first periodic table
Who is Dmitri Mendeleev?
This one is made of more than one type of atom: O₂ or H₂O
What is H₂O?
An element with 12 protons and 12 neutrons has this atomic mass.
What is 24?
Solids keep their shape because of this arrangement of their atoms.
What is tightly packed and linked together?
This is the smallest unit of matter.
What is an atom?
This is the horizontal row of elements on the periodic table.
What is a period?
This thing is NOT matter because it does not have mass or volume.
What is light (or heat, sound)?
Carbon (atomic number 6, atomic mass 12) has this many protons, neutrons, and electrons.
What are 6 protons, 6 neutrons, and 6 electrons?
This state of matter has particles packed so tightly that they only vibrate, this state has particles that slide past each other, and this state has particles that move freely and spread far apart

What are solids, liquids, and gases?
This part of the atom holds almost all of its mass.
What is the nucleus?
Elements in the same column of the periodic table share these.
What are similar properties?
This type of substance is formed when atoms bond together chemically, while this type is just a physical blend of substances without bonding.
