KMT
The theory explains how these tiny particles behave in solids, liquids, and gases.
Particles
The smallest unit of an element.
Atoms
Ice is water in this state.
A solid
This scientist created the first model of the atom.
Dalton
Ice melting is this kind of change.
Physical Change
As temperature increases, particles move in this way.
Faster
This element has the symbol O.
Oxygen
This process turns a liquid into a gas.
Evaporation or boiling.
The vertical columns in the Periodic Table are called these.
Groups
This kind of change produces a new substance.
Chemical Change
In a solid, particles do this instead of moving freely.
Vibrate in place
The number of different elements found on the Periodic Table.
118
This state of matter has a definite volume but no definite shape.
Liquid
Which scientist discovered shells of an atom?
Bohr
Burning wood is an example of this.
Chemical change.
This state of matter has particles that are far apart and move very quickly.
Gas
Gold, silver, and copper are examples of these kinds of elements.
Metals
The change from gas directly to solid is called this.
Deposition
The rows going across the Periodic Table are called these.
Periods
Breaking a pencil is this type of change.
Physical change.
The Kinetic Molecular Theory says that particle motion and this are directly related.
Temperature
The only element that doesn't have neutrons.
Hydrogen
Plasma is like a gas but has this extra feature.
Its electrically charged
The group known as the "noble gases" is in this column.
Group 18
Bubbling, color change, and heat production are signs of this type of change.
Chemical change
