What is a physical change?
300
This type of heating leads to the _____________ currents of our planets asthenosphere.
What is convection?
300
These elements are typically good conductors of electricity.
What are metals?
400
This determines the identity of the element
What is the number of protons?
400
Name this element:
What is Chlorine?
400
Mixing vinegar and baking soda to produce carbon dioxide gas is an example of this type of change.
What is a chemical change?
400
In the Earth's atmosphere, heating from the sun causes air near the Earth's surface to become warmer and less dense. This warm air rises, creating areas of lower pressure at the surface. Cooler, denser air then moves in to fill the areas of low pressure, resulting in what?
What is wind?
400
Silicon (Si) is an example of this type of element.
What is a metalloid?
500
The number of __________________ determines an atom's chemical behavior (what the atom will react with)
What is valence electrons?
