Chemical bonding

molecule- when any atoms join together

compound - when 2 different atoms join together

intermolecular forces -  forces between molecules

electromagnetic forces - between charges

2+ elements reacts = compound (either transfer or share electrons)

isotope- the same element witht he same number of protons but different number of neutrons so the mass number is different.

hydrogen = h2 to make it more stable 

ionic bonding

non metal and metal - create very strong forces (electrostatic) because they have force of opposite attraction

an ion…
