1s2 2s1 2p3
1s2 2s1 2p2
1s2 2s2 2p2
According to Hund's rule, how do electrons fill orbitals in a subshell?
Electrons fill orbitals in a subshell by pairing up first
Electrons fill orbitals in a subshell one at a time with parallel spins before pairing up.
Electrons fill orbitals in a subshell all at once
Electrons fill orbitals in a subshell in random order
Explain the Aufbau diagram and how it is used to determine electron configurations.
The Aufbau diagram is used to determine the electron configurations by counting the number of protons in the nucleus.
The Aufbau diagram is used to determine the electron configurations by following the filling order of the neutrons.
The Aufbau diagram is used to determine the electron configurations by looking at the number of electrons in the outermost shell.
The Aufbau diagram is used to determine the electron configurations by following the filling order of the orbitals.
State the Pauli exclusion principle and its significance in electron configurations.
The Pauli exclusion principle has no significance in electron configurations.
The Pauli exclusion principle states that electrons in the same energy level can have the same set of quantum numbers.
No two electrons in an atom can have the same set of four quantum numbers, leading to the organization of electrons in different energy levels and sublevels in electron configurations.
The Pauli exclusion principle only applies to electrons in the same orbital.
What is the electron configuration of oxygen?
1s2 2s2 2p4
1s2 2s2 2p2
