Answer:
=5 protons, 6 neutrons,5 electrons
All atoms of boron always contain 5 protons, as that defines its atomic number 5, Boron atomic number 5 has five electrons in its ground state.
Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form,all atoms of boron always contain 5 protons, as that defines its atomic number 5
The mass number for boron-11 is 11 (it's given to you), and recall that the number of protons plus the number of neutrons equals the mass number.
A 11B atom thus contains 11(mass number)−5(protons)=6 neutrons
The atomic number gives the number of protons,protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.
Boron number 5 has five protons and therefore as a neutral atom also has five electrons.
Boron has an electron configuration of 1s22s22p1
The most stable electron configuration for Boron is 1s2 + 3 charge,by losing three electrons Boron can achieve the stable electron structure of Helium
