NEET Chemistry Quantum Mechanical Model MCQ Question
Calculate the energy of the first orbit (n=1) for a hydrogen-like species with atomic number Z=4 using the given formula: E = -21810 * Z^2 / n^2 J. What is the energy?
-349,760 J
-54,525 J
-218,100 J
-87,240 J
Correct Answer
Detailed Explanation
Using the given formula E = -21810 * Z^2 / n^2 J, substituting Z = 4 and n = 1 gives E = -21810 * 4^2 / 1^2 = -349,760 J.
