Boron
doesn't follow the octet rule in that many of its compounds are electron deficient. The B has 3 valence electrons
and each F has 7 valence electrons, so 3*7=21+3 is 24 valence electrons in total. As the Lewis diagram will reveal, the B is connected to 3 atoms
and has no lone pairs, thus sp2.
Compound
B + 3F [arrow] BF3 Boron and fluorine yield boron (III) fluoride.
Boron has 2 shells altogether. 2 electrons on the first one and the remaining three on the second. Altogether boron (B) has 5 electrons.
Boron has 2 orbitals
All of them are "stable" elements in at least one isotope. The word "inert" is the term that applies to neon as it has completely filled atomic orbitals and obeys the octet rule.
The 2p orbitals.
BF. There is one Boron and one Flouride.
BF3
Covalent
Compound
It's a sp2 hybridisation.
B + 3F [arrow] BF3 Boron and fluorine yield boron (III) fluoride.
4 boron atoms
Borax has four boron atoms.
it is round
Boron has 2 shells altogether. 2 electrons on the first one and the remaining three on the second. Altogether boron (B) has 5 electrons.
