Question 3: Quantum (10 pts) The quantum energy levels of an electron in a box of length of Lare given by En = n2h2/8mL2 where n = 1, 2, 3, ..., h is Planck's constant and m is the mass of an electron. What is the smallest value that I can have if an excited electron in the box possibly produces visible light? Give you answer in units of meters or nanometers.
Which of the following set of quantum numbers (ordered n,l,ml,ms) are possible for an electron in an atom? Quantum Number Rules Learning Goal: To learn the restrictions on each quantum number. Quantum numbers can be thought of as labels for an electron. Every electron in an atom has a unique set of four quantum numbers. The principal quantum number n corresponds to the shell in which the electron is located. Thus n can therefore be any integer. For example, an...

Question 2 of 29 > Attempt 3 Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (11), the angular momentum quantum number (), the magnetic quantum number (me), and the spin quantum number (m) have strict rules which govern the possible values. Identify all allowable combinations of quantum numbers for an electron On= 3, C = -2, me = -2, m, =...
