To solve the problem, we need to determine the maximum number of electrons that can be present in an orbital of an atom.
1. Understanding Orbitals:
Each orbital can hold a maximum of 2 electrons. This is based on the Pauli exclusion principle, which states that no two electrons in the same atom can have the same set of quantum numbers. Therefore, each orbital can accommodate up to 2 electrons with opposite spins.
Final Answer:
The maximum number of electrons present in an orbital of an atom is 2 (Option D).
Which of the following is/are correct with respect to the energy of atomic orbitals of a hydrogen atom?
(A) \( 1s<2s<2p<3d<4s \)
(B) \( 1s<2s = 2p<3s = 3p \)
(C) \( 1s<2s<2p<3s<3p \)
(D) \( 1s<2s<4s<3d \)
Choose the correct answer from the options given below:
The energy of an electron in first Bohr orbit of H-atom is $-13.6$ eV. The magnitude of energy value of electron in the first excited state of Be$^{3+}$ is _____ eV (nearest integer value)
