How are molecules and polyatomic ions similar?
Molecules are atoms almost constantly bind to each other in nature to form groups. Polyatomic ions are covalently bonded groups of atoms that have a positivie or negative charge and acts as a unit. They are similar because they both contain groups of atoms. ...
How does earthquake energy travel in seismic waves?
A seismic wave is a mechanical wave - similar to a sound. Basically, the energy of the wave is propagated by groups of atoms hitting into the next group of atoms. ...
