Counting Atoms
Atomic Structure
100
The state of matter that has a definite (unchanging) volume and an indefinite shape (takes the shape of whatever container it is in)
What is a liquid?
100
This needs energy given or taken away to change
What is a phase of matter?
100
These are the basic building blocks of matter
What is an atom?
100
The amount of oxygen in H2O
What is ONE?
100
The positive piece of an atom, found in the nucleus
What is a proton
200
A solid forming when a liquid freezes is an example of this type of property of matter
What is a physical property?
200
A solid to a liquid
What is melting
200
He discovered neutrons
Who is Chadwick
200
The amount of hydrogen in CH4
What is FOUR
200
The negative piece of an atom, found orbiting the nucleus
What is an electron
300
Converting water into Hydrogen and Oxygen is an example of this kind of property of matter
What is a chemical property?
300
A gas to a liquid
What is evaporation
300
He discovered that atoms have a nucleus
Who is Rutherford
300
The amount of Iron in Fe2O3
What is TWO
300
The particle name for water due to having both hydrogen and oxygen in its formula
What is a compound?
400
This is made up of atoms and molecules. The particles that make it up are always in motion. This is made up of extremely small particles.
What is matter?
400
A solid to a gas
What is sublimation
400
He said that electrons orbit the nucleus like planets orbit the sun
Who is Bohr
400
The amount of ELEMENTS in C6H12O6
What is THREE (Carbon, Hydrogen, and Oxygen)
400
One Billionth of a meter (aka the measurement used on the atomic scale)
What is a nanometer?
500
At this goes up, so does the amount of movement among the particles of an object
What is temperature?
500
These are the six phase changes
What is Melting, Freezing, Condensation, Evaporation, Sublimation, Deposition
500
Current atomic theory has electrons surrounding a nucleus in this shape...not to be confused with a dragon or puppy on a partly sunny day.
What is a cloud?
500
The amount of Hydrogen in AMMONIA (NH4OH)
What is FIVE
500
The most important part of an element - it defines its properties. You change it, you change the element
What is the number of protons the element has
