How Many Neutrons Does Silicon Have?

Answer:

Silicon has 14 neutrons for this isotope.

Explanation:

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

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

                    Step-1:


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


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


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

                  

  Step-2:

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

From periodic table,


  ●Atomic number of silicon  is 14 .

●Atomic mass of  silicon is 28.09

●To find out mass number,we need to round 28.09 to a whole number.So,by rounding,we are getting mass number  of silicon.The mass number of silicon is 28.




                    Step-3:

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


●Number of neutrons=28-14=14
Therefore,the number of neutrons in silicon is 14 here for this isotope.Remember that neutrons are present in the nucleous of silicon and it's charge is zero.

● Number of electrons in silicon is 14.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of silicon.

●Number of protons in silicon is 14.Protons are present in the nucleus of silicon.
