Document Summary

The most common way to describe electrons in atoms according to quantum mechnics is to solve the schrodinger equation for the energy states of the electrons within the atom. When the electron is in these states, its energy is well defined but its position is not. The position of an electron in describes by a probability distribution map called an orbital. The solutions to the schrodinger equation are characterized by quantum number: n,l, and ml- A fourth quantum number, the spin quantum number(ms) specifies the orientation of the spin of the electron. Periodic properties and the periodic table (4. 1, 4. 2) The periodic table was primarily developed by dmitri mendeleev in the nineteenth century. Mendeleev arranged the elements in a table so that atomic mass increased from left to right in a row and elements with similar properties fell in the same columns. Periodic properties are predictable based on an element"s position within the periodic table.
