Question

For hydrogen like species, which of the following graphs provides the most appropriate representation of E vs Z plot for a constant n ? 

E : Energy of the stationary state, Z : atomic number, n = principal quantum number]

(1)

(2)

(3)

(4)

Answer 1

Correct option is : (2)

\(E_n = -13.6\frac{z^2}{n^2}\)

\(E_n \propto-z^2\)  

\(y = kx^2\)
