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

Answer:
Neon has ten neutrons for this isotope.

Explanation:

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

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

                    Step-1:


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


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


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

                    Step-2:

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

From periodic table,


  ●Atomic number of neon  is 10 (Ten).

●Atomic mass of  neon is 20.18

●To find out mass number,we need to round 20.18 to a whole number.So,by rounding,we are getting mass number  of neon.The mass number of neon is 20.




                    Step-3:

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


●Number of neutrons=20-10=10
Therefore,the number of neutrons in neon is 10 here for this isotope.Remember that neutrons are present in the nucleous of neon and it's charge is zero.

● Number of electrons in neon is 10.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of neon.

●Number of protons in neon is 10.Protons are present in the nucleus of neon.
