B
Boron has:- 1s2 2s2 2p1
1s2 2s2 3p4 3d1
LL
Yes, if the orbital is the outermost one that includes the valence electrons. Aluminum, for example, is such an atom, as is boron.
B
Boron has:- 1s2 2s2 2p1
Boron has 2 shells altogether. 2 electrons on the first one and the remaining three on the second. Altogether boron (B) has 5 electrons.
Electronic configuration of boron: [He]2s2.2p1.
orbital diagram for F
Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.

An orbital diagram is used to show how the orbitals of a subshell areoccupied by electrons. The two spin projections are given by arrowspointing up (ms =+1/2) and down (ms = -1/2). Thus, electronicconfiguration 1s22s22p1 corresponds to the orbital diagram:
Boron has 5 electrons and protons. Its Bohr diagram link is added in the related links.
The orbital diagram for MAgnesium is
Yes, if the orbital is the outermost one that includes the valence electrons. Aluminum, for example, is such an atom, as is boron.
