The K.E. of electron in He^+ will be maximum in — Atomic Structure Chemistry Question

💡 Solution & Explanation

Kinetic Energy is given by K.E. = 13.6 * Z^2 / n^2 eV. Since Kinetic Energy is inversely ∝ the square of the orbit number (n^2), it is maximized when n is at its minimum possible value. The minimum value of n is 1 (the first orbit or ground state), where K.E. reaches its maximum.
