What does the atomic mass of an atom tell us? (2 points) O How much the atom weighs
O The number of electrons in the atom
O Which row the element is in on the periodic table
O The number of energy levels in the atom

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?
