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

Answer:
Copper has 35 neutrons for this isotope.
How Many Neutrons Does Copper Have?


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.



How Many Neutrons Does copper Have?




                    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:


How Many Neutrons Does copper Have?

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.

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electrons.Here,each oxy
