【】How Many Neutrons Does Copper (Cu) Have?||Number of Neutrons in Copper

Answer:

Copper has 35 neutrons for this isotope.

Explanation:

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

To find out the number of neutrons  for copper,we have to have knowledge about atomic number,atomic mass,mass number of copper
.Click picture to see clearly.

                    Step-1:


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


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


●The masss number of copper is the number of protons plus neutrons of a specific isotope of copper.

                    Step-2:

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

From periodic table,


  ●Atomic number of copper  is 29.

●Atomic mass of  copper is 63.55

●To find out mass number,we need to round 63.55 to a whole number.So,by rounding,we are getting mass number  of copper.The mass number of copper is 64




                    Step-3:

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


●Number of neutrons=64-29=35

In another way,

●Mass number=Protons +Neutrons

Or,64 =29 +Neutrons

Or,64-29=Neutrons

Therefore,
Neutrons=35




Therefore,the number of neutrons in copper is 35 here for this isotope.Remember that neutrons are present in the nucleous of copper and it's charge is zero.

●Number of protons in copper is 29.Protons are present in the nucleus of copper.



● Number of electrons in copper is 29.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of copper.
