Answer:

Magnesium has twelve neutrons for this isotope.
How Many Neutrons Does Magnesium Have?




Explanation:

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





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



                    Step-1:


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


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


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




How Many Neutrons Does magnesium Have?




                    Step-2:

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






From periodic table,


  ●Atomic number of magnesium  is 12 (Twelve).

●Atomic mass of  magnesium is 24.31

●To find out mass number,we need to round 24.31 to a whole number.So,by rounding,we are getting mass number  of magnesium.The mass number of magnesium is 24.




                    Step-3:


How Many Neutrons Does magnesium Have?

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


●Number of neutrons=24-12=12
Therefore,the number of neutrons in magnesium is 12 here for this isotope.Remember that neutrons are present in the nucleous of magnesium and it's charge is zero.

● Number of electrons in magnesium is 12.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of magnesium.

●Number of protons in magnesium is 12.Protons are present in the nucleus of magnesium.

【】How to Convert Ethene to Ethanoic Acid or Acetic Acid||How Ethanoic Acid Is Prepared from Ethene

Image
Answer: To convert ethene to ethanoic acid,we will adopt four steps:              Step-1: Ethene reacts with HBr and we get 1-bromo ethane.            Step-2: 1-bromo ethane reacts with aqueous KOH and we get ethanol.            Step-3: Ethanol is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanal.            Step-4: Again,ethanal is oxidized by K₂Cr₂O₇ plus H₂SO₄ and we get ethanoic acid or acetic acid. Now see all the steps at a glance.

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...
