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

Answer:
Yes the given equation is balanced.
Explanation:
Chemical equation:
Fe + O₂ → Fe₂O₃
Balanced chemical equation:
4Fe + 3O₂ → 2Fe₂O₃
There are four iron and six oxygen atoms on both side of equation thus the given equation is balanced.
The given reaction also follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
This reaction is synthesis reaction:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
A + B → AB
