Because the spectra of elements is determined by the energy of transitions of electrons between two allowed quantum states. Since these energy differences can have only certain specified values, the spectrum consists of lines: The spectrum frequency values intermediate between the lines do not correspond to transitions between any two allowed quantum states and therefore do not appear in the spectrum
Proportion is the kind of emphasis that refers to the size relationship between components in a work of art.

element vs isotopes
I am pretty sure this has to do with the fact that there are differences between the elements.
Differences include mass; temperature; energy production; density; composition (percentage of elements).

Gases and metals
Each element has an atom that has different amounts of protons, neutrons, and electrons. This is the case for the element's atomic number and atomic mass. They are arranged by their differences on the periodic table of the elements. Most elements are metals. The three categories for the elements are metals, nonmetals and metalloids. ----
