Which statements accurately describe matter? check all that apply. only living things are made up of matter. matter is made up of tiny particles called atoms. atoms were discovered in the twenty-first century. atoms cannot be divided and still retain the properties of its original state. a single atom can be seen only with a standard microscope.

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
