【 】How Many Neutrons Does Magnesium Have?||Number of Neutrons in Magnesium
Answer:
Magnesium has twelve neutrons for this isotope.
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.
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.
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:
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.
