Renewable and Non Renewable Energy
What are some of the benefits of using renewable energy?
Renewable energy is clean, and will never run out.
What is an atom?
The smallest particle of matter.
What is energy?
The ability to cause change.
When an object creating sound waves moves towards you, is the frequency higher or lower?

Which type of shift is more common in the universe (red or blue)
What type of elements most frequently do a covalent bond?
Non metals.
What is a Carbon Footprint?
Your Carbon Footprint is the impact that your actions have on the environment.
What are the characteristics of metals?

What types of atoms usually use an ionic bond?
Non metals and metals.
What type of energy is nuclear?
(renewable or non renewable)
Depending on how you look at it, nuclear energy could be renewable or non renewable. For example nuclear energy itself is renewable, but the material used in a nuclear power plant is not.
How do you find out the number of neutrons an atom has?
Subtract the atomic number from the mass number.
What are examples of chemical potential energy?
Food, gasoline, and coal.
How does Hubble's Law support the Big Bang theory?
