Gravity
What types of forces hold things together?
● Intramolecular forces
○ Forces within the molecule that keep the molecule together
● Intermolecular force
○ Forces that exist between molecules
What predictions can we make about the forces of attraction that hold atoms together in a
molecule?
● Molecules that are attracted to each other can either:
○ Share electrons (covalent bonds)
○ Transfer electrons (ionic bonding)
● There are different types of forces
○ Intermolecular
○ Hydrogen bonds
○ Etc.
How is melting point related to the strength of electrostatic forces?
● Electrostatic - is the attraction or repulsion between charged particles
● Charged particles - are ions that either lose or gain electrons (and so become
charged)
● The attraction between oppositely charged ions are strong, and therefore their
melting and boiling points are high
How is Electrostatic Force defined?
● Electrostatic force - is defined as the force of attraction or repulsion between
charged particles due to their electric charges
● They are non-contact forces; they pull or push on objects without touching them
