a universal solvent
What water
a double bond is formed
what is when the molecules share 2 or more electrons
non polar covelant bonds form

non-polar molecules in association with water
What are hydrophobic (water fearing)
An atom that has an uneven amount of protons and electrons is charged/unstable
What is an Ion
