Which one of the following statements in relation to the hydrogen atom is correct?3s,3p and 3d-orbitals all have the same energy.3s and 3p-orbitals are of lower energy than 3d-orbital.3p-orbital is lower in energy than 3d-orbital.3s-orbital is lower in energy than 3p-orbital.

Statement-I: The orbitals having same energy are called as degenerate orbitals.Statement-II: In hydrogen atom, 3p3p and 3 d3 d orbitals are not degenerate orbitals.In the light of the above statements, choose the most appropriate answer from the options givenJEE Main 2024 (30 Jan Shift 1)AStatement-I is true but Statement-II is falseBBoth Statement-I and Statement-II are true.CBoth Statement-I and Statement-II are falseDStatement-I is false but Statement-II is true

Which of the following statements do not form a part of Bohr’s model of hydrogen atom?(a) Energy of the electrons in the orbits are quantized(b) The electron in the orbit nearest the nucleus has the lowest energy(c) Electrons revolve in different orbits around the nucleus(d) The position and velocity of the electrons in the orbit cannot be determined simultaneously.

Among the following pairs of orbitals which orbital will experience the larger effective nuclearcharge? (i) 2s and 3s, (ii) 4d and 4f, (iii) 3d and 3p

Which statement best describes the amount of energy released by gas-phase oxygen and sulfur atoms upon accepting an electron (electron affinities)? (A) O releases less energy than S because the smaller size of O causes greater electron-electron repulsion. (B) O releases less energy than S because O has a lower mass than S. (C) O releases more energy than S because the electron enters a 2p orbital in O but a 3p orbital in S. (D) O releases more energy than S because O has a larger effective nuclear charge Zeff than S.
