8 signs of life

Most common elements

Unequal number of protons and neutrons

2 atoms are unequal in attraction for valance electrons
more electronegative atom takes electron from the other atom

sharing electrons
completes outermost shell of all atoms present

1 atom is more electronegatively charged

forms between 2 polar compounds
forms between partially positive hydrogen and negative polar atom of other compound

shape determines....

polarity of water causes

caused by hydrogen
sticks in columb shape
hydrogen bonds with other water molecules

hydrogen bonds with other surfaces

how easy it is to stretch/break surface

stabalizes due to high specific heat
this allows life to exsist

amount of heat needed to change temperature of 1g of a substance 1degree celsius

solvent of life
