[Ne] 3s2 3p5
What is the element that has this configuration: 1s2 2s2 2p6 3s2?
What is Mg
In order to fill the 3d orbital, what orbital must be filled in first?
4s orbital
What is the electron configuration of F?
1s2 2s2 2p5
How many electrons can a s orbital have?
What is 2

[Ar] 4s2
What is the element with the following configuration: 1s2 2s2 2p6 3s2 3p3?
What is P
Out of these four orbitals, which one has the most energy: 1p 2d 3d 4s?
3d orbital
What is the element that has this configuration: 1s^2 2s2 2p6 3s2 3p6 4s2 310 4p6 5s2 4d2?

What is the Pauli exclusion principle?
states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
What is the electron configuration of Ni?
1s2 2s2 2p6 3s2 3p6 4s2 3d8
How many electrons can a f orbital have?
14
What is the electron configuration of Ba?
[Xe] 6s2
What is the element that has this configuration: [Xe] 6s2 4f14 5d9?
Au
What is the Aufbau principle?
The aufbau principle states that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. For example, the 1s shell is filled before the 2s subshell is occupied.
