intramolecular forces

Question 1

What is a force?

Answer 1

A force is any kind of push or pull on an object

Question 2

What is a contact force? List 2 examples

Answer 2

A type of force that requires objects to touch

ex: pressure, friction, air resistance, tension

Question 3

What is a non-contact force?

Answer 3

A force that can act on objects at a distance

Question 4

What is an intermolecular force?

Answer 4

A force acting between two or more molecules

Question 5

What is an intramolecular force?

Answer 5

A force acting within an atom, ion, or molecular

Question 6

What does Coulomb’s law state that describes intramolecular forces? (2)

Answer 6

1) The charges in an atom or molecular attract if they are different. Attraction is greater with higher charges
2) Charges on an atom push apart if they are the same

Question 7

Why do electrons stay a certain distance away from the nucleus?

Answer 7

Otherwise, protons and electrons would crash into each other because of the attraction of their charges (Coulomb’s law)
