Exam Set Questions And Answers

What is the Blackbody Paradox? {Ans: If an object is heated enough, it will start to glow/emit light}Is there a difference in the Zeff of cations and anions? {Ans: Cations normally lose an electron to go down an energy level and become stable, making their Zeff increase (closer to nucleus) and atomic radius decrease. Anions normally gain an electron to go "up" an energy level and become stable, making their Zeff decrease (farther from nucleus) and atomic radius increase}Differentiate Z⁺ and Zeff⁺ {Ans: Z⁺ is the true nuclear charge AKA the atomic number Zeff⁺ is the effective nuclear charge that changes with attraction or repulsion between electrons and nuclei}What does 𝚿 mean? {Ans: Nothing physically observable}When electrons are ejected off a surface, what does left over energy turned into? {Ans: Electron kinetic energy}What are the four properties of wavelength functions? {Ans: 1) 𝚿 must be finite at all points in space (only zero at nodes where no electrons are present) 2) 𝚿 must be single-valued 3) 𝚿 must be continuous 4) 𝚿² = 1}
