【】How Many Neutrons Does Boron Have||Number of Neutrons in Boron

Answer:

Boron has six neutrons  for this  isotope.

Explanation:

Hello, chemistry lover! today we are going to find out  how many neutrons boron have in just 3 steps.

To find out the number of neutrons  for boron,we have to have knowledge about atomic number,atomic mass,mass number of boron.

                    Step-1:


●The atomic number of boron is the number of protons in boron's nucleus.


●The atomic mass of boron is the average number of  protons plus neutrons of all the isotopes of boron.


●The Masss number of boron is the number of protons plus neutrons of a specific isotope of boron.

                    Step-2:

We need to convert atomic mass of boron to mass number of  boron by rounding if necessary (In case of fraction) .

From periodic table,


  ●Atomic number of boron  is 5(five).

●Atomic mass of  boron is 10.81

●To find out mass number,we need to round 10.81 to a whole number.So,by rounding,we are getting mass number  of boron.The mass number of beryllium is 11.




                    Step-3:

By the difference between mass number and atomic number of boron,we get the number of neutrons in boron.


●Number of neutrons=11-5=6
Therefore,the number of neutrons in boron is 6 here for this isotope.

● Number of electrons in boron is 5.Remember that number of electron equals to proton in a neutral atom.

●Number of protons in boron is 5.
