Solved Correct 2025-2026 Edition.
Energy of the Electron - Answer E= (-kZ^2)/n^2

z=Atomic number



Difference in electron energy - Answer E1-E2



Larger core charge - Answer Larger 1s energy



Ionization Energy is equal to Coulombic Potential Energy - Answer IE=V=(kq1q2)/d



Total Potential Energy - Answer V1+V2+V3



Calculate Core Charge - Answer Atomic #- # inner electrons



Core Charge Trends - Answer Increases going left to right across a period

Same going down a group



Covalent Radius - Answer One half the distance between the nuclei of 2 identical atoms
when joined by a covalent bond



Radius Trend - Answer Increases down a group and from right to left



Large Core Charge - Answer Small radius



Ionization Energy Decreases - Answer Atomic radius increases



Cation (positive charge) - Answer Lose electron

decrease radius

increase IE

, Wavelength - Answer nm



Frequency - Answer Hertz, s^-1



Speed - Answer Wavelength times frequency



Rydberg Equation - Answer



Energy of Photon - Answer E=IE+KE



V=Energy Level=-IE - Answer V=Energy Level= --Ionization Energy
