【 】How Many Neutrons Does Magnesium Have?||Number of Neutrons in Magnesium

Answer:

Magnesium has twelve neutrons for this isotope.

Explanation:

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

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

                    Step-1:


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


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


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

                    Step-2:

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

From periodic table,


  ●Atomic number of magnesium  is 12 (Twelve).

●Atomic mass of  magnesium is 24.31

●To find out mass number,we need to round 24.31 to a whole number.So,by rounding,we are getting mass number  of magnesium.The mass number of magnesium is 24.




                    Step-3:

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


●Number of neutrons=24-12=12
Therefore,the number of neutrons in magnesium is 12 here for this isotope.Remember that neutrons are present in the nucleous of magnesium and it's charge is zero.

● Number of electrons in magnesium is 12.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of magnesium.

●Number of protons in magnesium is 12.Protons are present in the nucleus of magnesium.
