Use energy level diagrams for atomic orbitals v. s molecular bonding/anti-bonding orbitals to explain which has a higher first ionization energy, atomic h or molecular h_2.

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Argon, neon, and xenon are examples of

Carbon 14 is a naturally occurring stable
