Atom
Matter is all "stuff" that has a _____ and ______.
Mass (you can measure it) and Volume (takes up space)
This element contains only 1 proton and is the lightest one on the Periodic Table.
Hydrogen
Elements on the Periodic Table are organized into vertical columns called...
Groups
Chemical Symbol
A letter used instead of an element's name.
The positively charged particle in an atom's nucleus.
Proton
Matter with particles that hold their shape and volume, and do not move easily.
Solid
A highly reactive element, it easily combines with most other elements to form molecules. It is the most abundant element on Earth, making up 48% of its crust, atmosphere, and surface water.
Oxygen

Neutron
Matter with a set volume of moving particles that move easily to match the shape of a container.
Liquid
Halogen gas used as a bleaching agent, a component of common table salt, also used as a disinfectant and water purifier
Chlorine
The elements on the Periodic Table are grouped together into families based on...
Shared physical or chemical properties.
Isotopes
Atoms of an element with different numbers of neutrons in the nucleus
The smallest particle of an atom, negatively charged, and found in orbit outside the nucleus.
Electron
When a substance goes from a solid to a liquid, or from a liquid to a gas, etc.
Possible answers: state change, physical change
Inert "noble" gas. Does not react to other elements naturally, but glows red when electricity passes through it.
Neon
The Period table contains 92 natural elements. Why are there over 100 elements on the chart?
Some of them are artificial/made by scientists.
Thermite Reaction
A chemical reaction that produces heat, light, and new substances.
2Al(s) + Fe(2)O(3)(s) > heat > 2Fe(s) + Al(2)O(3)(s)
