Among the following, the correct statement(s) for electrons in an atom is(are)
Solution:
(1) Uncertainity principle talks about probability of finding electrons in different regions around the nucleus rather than definite paths.
(2) With increase in distance of electron from the nucleus, its energy increases.
(3) Energy of electron \(E_n=-13.6 \times \frac{\mathrm{Z}^2}{\mathrm{n}^2} \mathrm{eV} /\) atom.
(4) Velocity of electron \(V_n=2.19 \times 10^6 \times \frac{Z}{n} \mathrm{~m} / \mathrm{sec}\).
