What is one way forces act on atoms

Forces cause bonds to form.

How are models affected by new evidence

Models are changed if they don't fit new data.

What makes balancing redox reactions different from balancing other reactions

Balancing redox reactions is different from balancing other reactions because both the number of atoms and the amount of charge must be balanced.
