How Many Neutrons Does Oxygen Have?


Answer:
Oxygen has eight neutrons for this isotope.

Explanation:


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





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



                    Step-1:


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


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


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




How Many Neutrons Does oxygen Have?




                    Step-2:

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

How Many Neutrons Does Oxygen Have?






From periodic table,


  ●Atomic number of oxygen  is 8(Eight).

●Atomic mass of  oxygen is 16.00

●To find out mass number,we need to round 16.00 to a whole number.So,by rounding,we are getting mass number  of oxygen.The mass number of oxygen is 16.




                    Step-3:


How Many Neutrons Does oxygen Have?

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


●Number of neutrons=16-8=8
Therefore,the number of neutrons in oxygen is 8  here for this isotope.Remember that neutrons are present in the nucleous of oxygen and it's charge is zero.

● Number of electrons in oxygen is 8.Remember that number of electron equals to proton in a neutral atom.

●Number of protons in oxygen is 8.

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

  How many valence electrons does C6H12O6 (glucose) have ? Answer : In  C₆H₁₂O₆ ,we get 6 carbon atoms , 12 hydrogen atoms and 6 oxygen atoms. Firstly, carbon is an element of group 4A,so it has 4 valence electrons. Secondly,Hydrogen is an element of group 1A.So it has one valence electrons. Thirdly, oxygen is an element of group 6A .So it has six valence electrons. For   C₆H₁₂O₆ , 6 C = 6 × 4 = 24 12 H =12 × 1 =12 6 O = 6 ×6    = 36 Totally, we are getting 24 + 12 + 36 = 72 valence electrons in glucose (C6H12O6). Next
