New cards

Ionic Bonds

Form between the positive and negative charges of ions.

2
New cards

Covalent Bonds

  • “Sharing” electrons

  • Polar

- shared electrons are unequally pulled towards the atoms

  • Nonpolar

- made between atoms of the same element, or elements that share electrons equally


3
New cards

Hydrogen Bonds

  • Slight positive/negative charges caused by polar covalent bonds

  • Weak “bond” - technically a strong “intermolecular force”


4
New cards

Van Der Waals Interactions

  • Based on electrondensity around an atom

  • also “intermolecular forces”
