What is the Bohr Model?
This type of bonding is present in the molecule NaCl.
What is Ionic Bonding?
This is the name for the molecule H2O.
What is Water?
This type of change is represented by a solid melting into a liquid.
What is a Physical Change?
This state of matter commonly has a definite volume and a definite shape.
What is a Solid?
This philosopher created the first model of the atom where he theorized that all matter is made up of indivisible particles.
Who is Democritus?
This type of bond is created by sharing electrons via shell overlap.
What is a Covalent Bond?
This is the name for the molecule MgCl2
What is Magnesium Chloride?
This chemical property is demonstrated by burning wood.
What is flammability?
This state of matter takes the shape of the container it is placed in.
