How Many Neutrons Does Scandium Have?


Answer:

Scandium has 24 neutrons for this isotope.

Explanation:

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






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



                    Step-1:


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


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


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



How Many Neutrons Does scandium Have?




                
    Step-2:

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






From periodic table,


  ●Atomic number of scandium  is 21 .

●Atomic mass of  scandium is 44.96

●To find out mass number,we need to round 44.96 to a whole number.So,by rounding,we are getting mass number  of scandium.The mass number of scandium is 45.




                    Step-3:


How Many Neutrons Does scandium Have?

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


●Number of neutrons=45-21=24
●Mass number=Protons +Neutrons

 Or,45 =21 +Neutrons

 Or,45-21=Neutrons

 Therefore,
Neutrons=24


Therefore,the number of neutrons in scandium is 24 here for this isotope.Remember that neutrons are present in the nucleous of scandium and it's charge is zero.

●Number of protons in scandium is 21.Protons are present in the nucleus of scandium.



● Number of electrons in scandium is 21.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of scandium.

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 electron...
