How Many Neutrons Does Calcium Have?

Answer:
Calcium has twenty neutrons for this isotope.

Explanation:

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






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



                    Step-1:


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


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


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



How Many Neutrons Does calcium Have?




                    Step-2:

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






From periodic table,


  ●Atomic number of calcium  is 20 .

●Atomic mass of  calcium is 40.08

●To find out mass number,we need to round 40.08 to a whole number.So,by rounding,we are getting mass number  of calcium.The mass number of calcium is 40.




                    Step-3:


How Many Neutrons Does calcium Have?

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


●Number of neutrons=40-20=20
Therefore,the number of neutrons in calcium is 20 here for this isotope.Remember that neutrons are present in the nucleous of calcium and it's charge is zero.

●Number of protons in calcium is 20.Protons are present in the nucleus of calcium.



● Number of electrons in calcium is 20.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of calcium.

Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation: Now I am going to show you how to find valence electrons in selenium  in just 5 steps. Add caption              Step-1: First, find the atomic number of  selenium  from periodic table. From periodic table ,we see that the atomic number of  selenium  is 34.                  Step-2: We know that the atomic number of  selenium  is 34.So  selenium  has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1.

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
